Gia May 25 2026 2:03 am Definitely the best season!! I can relate to this kdrama so well: in their 30s and having a crush with a younger man. Hahaha

Diane May 19 2026 11:01 am Yumi's Cells is definitely one of my favorite K-Drama, and Shin Son Rook is mu favorite male lead for Yumi. I really love their chemistry and I felt how deeply inlove they are with each other. I even rewatched the 7th and 8th episode. I can't get over it! I just love it so much. I don't even want it to end!!

Ciaa May 18 2026 12:25 am I only have 1 complain.

Why 8 episodes !!! Love it so much that I keep on watch it on repeat !

PS: thought the exes gonna appears !

Panseokah May 15 2026 6:11 pm One of my favorite dramas ever. I loved every episode of each season. The acting, lighting, clothing, and love. Yumi worked so hard in her professional & love life.

YUMI biggest supporter May 08 2026 8:50 am It's perfect from start to the end. The only thing I complain is how we only get 8 episodes for this last season ? Now i have withdrawal syndrom after it's finished. Can't say goodbye to Yumi and all of her cells. I hope someday TVING can make another bonus season for us.

Cherry May 08 2026 6:10 am Kim Go Eum is my favorite. Very good series. Expecting more series and movies to come out for Go Eun.

Yumi May 07 2026 9:05 pm With all the age compatible actors, why do they keep paring up older female protagonists with younger male protagonists. Not complaining about their acting skills. It’s just cringey when the age difference is so big (10 years!!l.

Taylor May 06 2026 11:46 am This should've been a 10 or 12 episodes omg we were robbed with their romantic scenes :') but finally yumi end game (well we all know lol) and as usual, Yumi's Cells never disappoint. Been a fan since season 1 and the storyline is so well written! Thank you for everything! Will miss this so much :(

Bela May 06 2026 3:01 am I have watched Yumi Cells S1 and S2, and i am a big fan of the storyline and plot since the beginning. For Season 3, i could say thank you very much for everyone involved in this drama, i really happy for Yumi and Soonrok. What an impeccable acting both KGE and KJW until the end. Writer-Nim, both the drama and the webcomic, thank you so much for bringing us the story of Yumi and her cells <3 <3 <3

Tika Octariza May 05 2026 7:55 pm The perfect K-drama to wrap up the previous seasons. Everything was done perfectly, and this time "the cells" got plenty of screen time. The chemistry between Go Eun and Jae Won was spot-on, I hope to see them act together in another drama. Even though there are only 8 episodes, but I’m quite satisfied with how the entire drama was put together. As a noona watching this, I could really feel Yumi’s “Butterfly Era.” The ending of episode 8 felt warm and touching—I cried tears of joy. I’ll keep rewatching Yumi’s Cell Season 3 over and over.

Christian May 05 2026 1:50 am Even though it was too short, this was such a well-made drama. The chemistry between the two leads was off the charts. Kum Jae Won played Soon Rok perfectly. I will miss this drama but it brought joy to my life every Monday.

Chloe May 05 2026 12:01 am First of all, I want to express my gratitude to Kim Go-eun for portraying Yumi so beautifully. Her performance was, as always, great.

Yumi taught me a lot - how to chase my dreams, how to walk away from relationships when I know I deserve more, how to set firm boundaries, how to overcome heartbreak and many more.

Most importantly, this series reminded me that I am the leading character of my own life.

It was such a joy to watch the cast, as it felt like everyone truly enjoyed making the show. I’m so happy with the ending, Yumi truly deserved someone as caring and fun as Soon-rok and she did so many healthy choices in Season 3. Yay!

I will miss this show and will definitely be rewatching it!

Thank you all! Great work!

Caela May 04 2026 3:45 pm I love the chemistry between Yumi and Soon Rok, I think they look good together, and how shin soon rok is not afraid of expressing his feelings. He is young but mature and it’s sexy. I wish there was more episodes. Let me not forget, the way he touched her head while kissing and caressing her hair gets me everytime. I find that such a romantic thing, maybe am just lonely ?

sachi May 04 2026 10:35 am Yumi's cells has been such a solid all rounder, one of my top fav kdramas and one of the very few that keeps the fun in every season. My only wish was that season 3 should have been longer. I do think they got the plot bang on but I feel like if the season was a bit longer we could have seen more comedic and wholesome moments, which make this show so good.

On a real note, it's so rare to see kdramas continue to s3 with quality and the same integral cast so I'm grateful Kim Go Eun stook with the show to finish the story. Highly recommend watching this show from season 1-3!! So jealous of those who can watch it all without any breaks in between haha :)

Lea Apr 30 2026 4:29 am I’m a bit surprised that most dramas right now have around 12 episodes, while the one I’ve been waiting four years for only has eight!!! It’s even more frustrating when her past relationships got 14 episodes each, but her story with her husband has so much less time. ?

With only two episodes left, I can’t help but feel like the ending might be rushed. ?

Yumi Cells you will always be my favourite!!!!! ?

The best season please extend Apr 30 2026 3:05 am oh my good the ep 5 & 6, so good I kept on watching Soon Rok's scene when he was processing his emotion huhu I love it so much please extend ?

rara Apr 28 2026 11:00 pm I'm addicted to this season, i keep repeating ep 5 and 6. But, why only 8 eps huwaaaa ... we need moreeee

Gia Apr 28 2026 8:14 pm Why only 8 episodes?? First and second season has 14 episodes.. i want more..

Yasmin Apr 28 2026 6:26 pm Until episode 8. Why it's too short? How I love the season 1 and 2 the more I'm addicted to season 3. The story is too good to end soo early. How i wish to see more happy moments and how the relationships grow stonger between them.Soon Rok and Kim Yumi's chemistry is too perfect.

jkanak Apr 27 2026 7:38 pm I love this show! I've been reading Yumi Cell's since I was in high school, and they got Soon Rok perfectly! I know everyone loves Woong or Babi, and even though Babi is still my personal favorite, Soon Rok is who my girl Yumi deserves! The pacing is so good, but I do wish they put new songs for this season instead of the previous ones. 10/10

So happy Apr 27 2026 10:26 am Ep 5&6 is just so good I don't want this to end. How can the last season just 8 eps???? I mean this is when Yumi will finally get her happy ending after failed relationship--why does it have to be so shortttt. I want more episodes of Soon Rok and Yumi pls.

Hyena Apr 26 2026 5:26 am I love their chemistry so much! They look so cute together!

Best Kdrama of 2026 Apr 26 2026 12:41 am This is one of the best korean drama of 2026, the pairing and chemistry of the lead couple is beyond amazing. Episode 3 and 4 was chef's kiss. I can't wait to watch episode 5. Looking forward for both of their awards soon such great lead and drama.

Chloe Apr 22 2026 4:11 pm Giggled all episodes without stopping... I really adore how Yumi hated SoonRok in the beginning. I think she liked him right from the start.

Regarding SoonRok, he likes Yumi too, especially when he decided to visit her on his birthday. For an introvert person to do it, wow, it is a sign.

I am really curious about what will happen next.

So sad it is only 8 episodes... I need more! And it will be so sad to say goodbye to Yumi!!!

EunHee Apr 22 2026 10:31 am I don’t mind the 10yrs age gap! I really hope this season, Yumi will have a happy ending!

Also, I hope there will be a cameo for the 1st and 2nd season’s leading man??

Daebakk Apr 22 2026 12:39 am Wow I love this Season 3, one of the best I've seen. Episode 1 and 2 were so refreshing and I love the chemistry of the lead. It is so good to watch. I can't wait to watch episode 3 and 4. Such an Kdrama of this year.

Ok Apr 21 2026 1:09 pm Just my opinion… the first two episodes of Season 3 were pretty boring to me, and judging by the ratings for Episode 2, I don’t think I’m alone on that. Episodes 3 and 4 were soooo calm they honestly felt like a lullaby — I was almost falling asleep by the end of Episode 4. I feel like Season 3 is missing some charisma. You know when someone is attractive but just not that interesting? It’s kind of like that. The actors are good, and Soonrok is actually doing better than I expected, but nothing is really grabbing me — it all feels a bit too plain. I had a totally different vibe when I read the webtoon. Yumi and Soonrok felt way cuter and lighter there. I’m not sure I’m loving this adaptation… I’ll keep watching the next episodes, but so far… ??

rara Apr 21 2026 1:24 am know what? I feel like I'm the one who is in love now. I love this s3 so muchhhh

Fen Apr 19 2026 9:15 pm I have trauma on season 1 and 2, so please on season 3 please be nice ????❤️

lml Apr 17 2026 9:54 pm I'm so excited for the next episodes!

Armandia Apr 16 2026 1:26 am I've read the manhwa till the end and I can say that Yumi being pissed off by Soon Rok's behaviour is really original and funny. The cursing cell is now my favorite ❤️?

ALaska-Kid Apr 15 2026 5:28 pm Oh, Yu mi, you're finally back!

Mahum Apr 15 2026 12:47 pm Season 3 is going strong so far. Obviously the 1st and 2nd season was spot on . This is also matching the vibe.. the star of the show are obviously the cells. I'm at episode 2 of this season...Looking forward to it

Daebakk Apr 15 2026 7:19 am Wow I started watching episode 1 of Season 3 without watching Season 1 and 2. And I can say, this is so refreshing I love how the storyline goes and SSR character matchly provide great chemistry with the dislike that KYM is building. Idk but probably this couple will be one of those well loved lead stars in a series. This is very well acted and I can't wait to watch the rest of the episodes of this Season 3.

Hahaappy Apr 15 2026 4:09 am Hi can i ask if it is okay to watch without watching the two season?? I watcb episode 2 of season one i haven't finish it..

Mary Apr 07 2026 7:00 am The timing is perfect and great. My emotions have been completely reset which means I will be able to hop on to Yumi's life again and experience her new love. The first season came in 2021 and we all fell for Woong. We never got over the breakup. S2 came the very next year and many of us harboured those emotions and still went along to see what Yumi will undergo with Babi. Now it's been 4 years so I'm personally interested in this chapter. Having completely void myself of the previous seasons. I am finally able to knock off the male leads who were only extras and embrace Yumi who is main character and whose emotions alone matter. Let's see how the story is portrayed.

Koni Mar 29 2026 7:03 am Love this drama and the main character Kim Go Eun..If ever there will be Yumi’s Cells S4. Can we have Lee Min Ho as her husband??

Banana Uyu? Mar 22 2026 9:05 am I won't expect more because the drama will be good, but I hope the soundtrack is no less good than the previous season so I can get the feeling (sad because the soundtrack of Korean dramas is not as good as it used to be these days)

Aoi Mar 22 2026 4:36 am Though she will end up with this new male lead, I'm still hoping Ung and Yumi will be back together and fix what was lacking to their relationship to make it work until they finally got married, I know it's impossible but I feel sad about the ending, maybe because it's relatable? Maybe because it's quite similar to my situation in the past? My personality is quite similar to Yumi, I actually regret watching this drama quite a bit I always cry while watching this drama. I just hope that Yumi will finally find her man who she will end up to be with for the rest of her life.

jia Mar 14 2026 9:24 am I was hoping for Hae In to be Soonrok, but still soooo excited to watch this!!

peoplez Mar 09 2026 4:09 am @ Animo lol, of course Babi will be removed. He is the main lead Only for season 2. Just as Woong is the main lead only for season 1. Soonrok is the ultimate endgame, and we want the drama to be faithful to the source material because it is a masterpiece. We have been so mad that Soonrok's webtoon moments and scenes had been used by Woong and Babi in the drama. Regardless I hope they create new moments that is even better here.

Animo Mar 06 2026 7:55 am I really like this series, all the characters, and the cell concept. I love the whole storyline and the overall idea. But when it comes to the love factor, I think there is too much confusion. It does make the story more interesting, but I still feel that as the main lead, Yu-mi should choose Ba-bi. The writer made it more complicated, and Season 3 will probably create more suspense. Still, I hope Yu-mi ends up with Ba-bi. Please don’t remove Park jin young, Ba-bi as a main character.

Farnaz Feb 09 2026 4:07 pm Can't w8 4 season 3??i loveeeeee it

noinoi Nov 18 2025 9:52 am Kim Jaewon as Shin Soonrok? So we have Cheon Sanghak here? Lol. Then if Seo Saeyi appeared this season, we will have Ryu Eunjung and Cheon Sangyeon too. Is there perhaps a parallel between Yumi's Cells and You and Everything Else? Haha. Both Yumi and Eunjung are writer as well!

Khushi raI Sep 02 2025 4:33 pm Just finished watching this drama I watched this drama for ahn bohyun it's season 1 didn't watch cause of his hair style but this year I just fall in love with his acting, started to watch all his drama end up watching this too totally loved and Emphasize his character I was rooting for woong all the time. I don't know about s3 has woong appearance or not but eagrily waiting for it !

Ri Aug 22 2025 7:31 am Kim Jae Won as Soon Rok. Yeayyy can't waitttt :") 2026 still far away, can't wait anymore huhu

blah Aug 10 2025 8:57 am i don't have problem with the male lead, he got the visual and height, close to the image of cartoon soonrok to be fair, people have to remember this is yumi's story, she is the only lead in this story, of course the casting director can't cast one of those A list actors as it would overshadow the focus of the plot and very unlikely any A list actors want to take the second biller in a woman centered drama

Edbert Ballente Aug 10 2025 12:45 am Season 1 made me alot of realization it feels like getting back to my feet i cried a whole time as i watch it. Season 2 almost have of episode i already watched but i didn't finish because i am not ready of the emotion gave to me during the season 1 it takes alot of courage for me to finish the whole season 1 so im ready for the pain although I watched the last episode it's more like some kind of cheat and just like the season 1 it gives me a lot of realization and mixed emotion I promise myself to finish the whole season 2 when season 3 will be release

Mi mi mi Aug 04 2025 2:41 pm Not to be a cyber bullying and all but after the long wait , this is the ML we get !!! I am seriously pained and I hope it isn't a waste of my time and emotions

bruh Jul 27 2025 10:23 pm out of all the actors they could've chosen, they chose jae won for soon rok....? I hope it's good then...

Marrah Jul 20 2025 3:54 am can't wait for season 3!! 2026 is way too far away tho

Namj Jul 04 2025 11:36 am I thought shin son rok should be someone.. much better than jinyoung & bohyun..uwaaaaaa stressss.. u break viewer heart two times and this what pd give us at the end... T.T

Audray Jun 28 2025 2:31 pm I just finished watching season one and two, so am super pumped.
