This causes cracks in her daily life and the balance of her life begins to shake. Sunwoo Chan works as a character designer at a world famous animation studio.

haechi Jun 02 2026 5:10 am I Love this soooo much !! I highly recommend watching this; you won't be disappointed.?‍↕️??

Narukii May 26 2026 11:45 am Absolutely good, I was teared when I was watching this. Their plot, cast, and others are enjoyable. Best k-drama of the year, and go watch if you haven't !!!!!!!!!!!!!. Honestly, it deserves more episodes as the k-drama incredibly good.

Bagu May 10 2026 4:52 pm One of my favorite dramas of the year so far. The storyline is so good — you never know what to expect, and even until the very end, there are still surprises that turn out differently from what you imagined.

I especially love how the story gives attention to characters beyond just the main leads, which is something I value a lot in a drama. That said, my favorite couple was Ha Young and Tae Suk, and I honestly wish they had gotten more screen time and more romantic scenes together.

I really like Han Jin Hyun, and I hope she gets many more roles and eventually lead characters because she steals every scene she’s in. Needless to say, Lee Sung Kyung and Chae Jong Hyeop were amazing as always.

Chinecherem May 08 2026 9:53 am Perfect story.... I loved episode 1 to 3 and then stopped after few days I resumed from episode 4 to the end. I enjoyed it so much... A story full of family love, bonds and healing

Queenie May 04 2026 1:16 pm Loved Jong Hyeop and Sung Kyung in this series. I pick my shows according to how much I liked the actors. I've seen Sung-Kyung before and like her acting, but I haven't seen much with Jong Hyeop in a series, so I will be looking for more of his series. I always watch k drama's with happy endings and this one didn't disappoint! I actually enjoyed all the story's main actors!

Chan May 02 2026 6:35 am I love this drama so muchh. The ending is the bestt!!

rayha_22 Apr 27 2026 5:05 pm It's really good kdrama in 2026 for me, I have been waiting to see a drama like this for a long time, and it came in a time that I feel crying so it healed me. This is the definition of perfect drama, perfect actors, it's just perfect in many ways I love this

RachelM Apr 26 2026 7:24 am 1 word, just perfect!!!

Well, I’m a mellow person but I literally cried my eyes out in most of the episodes.

Round of applause for all the cast, especially Lee Sung Kyung!!!

Liliana Apr 25 2026 6:15 am All the couples in this drama are all perfect for each other. Aaahh when will i find guys like Chan, Mr. Yeon, Yoogyum and Mr. park Watching this kdrama made my standards for men go super high lol

Lana Apr 19 2026 2:51 pm The last episode aired a few weeks ago and I Still can't move on. A beautiful story that brought joy, tears, and reflection on different seasons of life. This cast is absolutely brilliant. Definitely the one of the best dramas of 2026.

Justine Apr 15 2026 9:37 am This warms my heart in many ways I cannot imagine. I cried in each episode, not just because of sadness and misery, but of wonderful things as well. Easily, one of the best Korean dramas in recent years! Thanks to the whole cast and crew!

PS. This is my first time giving a review here at AsianWiki. I truly want to express my feelings for this drama! I am an avid fan of Korean drama and music from the Philippines since 2015.

Kdramafan Apr 03 2026 7:26 pm I have never watched a drama that was so well-written, no big villains, but each main and side character was so well-developed! Love the chemistry between each set of characters, this has become my all-time favorite drama showcasing heartwarming theme, it's like comfort drama, comfort couples. I don't care what ratings they get, but this drama deserves a top spot! Good job to the cast, director, and producer for this masterpiece

seokjinie Mar 28 2026 7:09 pm Ep 10 and 11 shattered me....

This drama is a masterpiece!!!

I hope they give all the characters a happy ending

HYJ Mar 28 2026 1:31 pm This drama... I have no words.

It is a masterpiece. Ep 10 and 11 hit me like a truck. I was crying and sobbing the whole way through. You can feel the love that this series was given by all the actors, the producers, the writer, all the staff.

It is a beautiful crafted story with many moments of growth amongst all the different characters. The minor details and cinematography is tastefully done where if you notice and connect the dots, it enhances the storytelling that much more.

There are moments of breathtaking scenes and shots where it captures the emotions of the actors so well, you can't but feel it as it was yourself going through their pain and love.

The skillfully placed hints or eastereggs of connections and details show that it is more than just a story being told, but instead is a story being shown! Thank you for this drama, I will really miss it once it ends next week on ep12.

I am ready for the final wave of emotions and story left to be told in the last episode, I will also have my popcorn and tissues ready!

Nyahhh Mar 28 2026 7:15 am So in love with the story!! This is the first kdrama i love all the couples. I love all the cinematography, the atmosphere it gives.

Lee Mar 26 2026 6:38 pm Love love this series. Beautifully written and acted. Thoughtful and love every character! Thank you to all who worked on this project from bottom up but all equally important to create this lovely drama.

Phew Mar 26 2026 2:08 pm I'm so grateful to the writer for creating such a beautiful drama. I love how the story builds slowly and touchingly. The plot is refreshing, and the mystery element keeps it from getting boring. I also love their dialogue.

Thank you also to the production team for the beautiful and comfortable cinematography. I felt the warmth in every episode.

Chae Jong Hyeop and Lee Sung Kyung have perfect chemistry. Lee Sung Kyung, in every act and on your face, I feel the trauma building slowly and gradually returning to cheerfulness. Chae Jong Hyeop, I feel his cheerful gaze masking his sadness, and his skinny physique shows lingering trauma.

Such a greet drama!!!

Es El Mar 24 2026 2:04 am I really like all the character development in this melodrama. There are moments that’ll make you tear up but also leaving you feeling a sense wholesomeness. I love the personality of the ML.

Sushi87 Mar 23 2026 3:50 am CJY fantastic acting in ep 7 and 8. He showed depth here. Also love younger sisters love stories. Grandma Nanakim is a lovely character but I wish tbey just made her a strong character and not have an overly used medical issue subpliot. Coffee Shop ahjussi is lovable too.

Ebi Mar 22 2026 3:21 pm I love the warmth I get from seeing this drama,no extra stuff going on very precise and with the right amount of suspense, everyone delivering their roles with a touch of excellence.

Lee Ash Mar 21 2026 5:06 pm CJY yogshi,always plays his characters like a pro I love the match with LSK she always has chemistry with everyone. I love the back story the careful layering of events and suspense. Being that life has been forgetful for me, CJY shows me what I need to be and LSK shows me what I want to be. I love the family makeup supporting each other and stuff. I love how they show how all individuals carry their scars, forgive the flaws of their loved ones and see life a positive lights no matter what.. That's the kind of family I want someday. All in All.i give the drama 100pts. It's warms, it's sparkly, it's fun and filled with the right emotions. Love love love it!!!!

A Mar 21 2026 12:45 pm No way its only 12 eps

Sushi87 Mar 20 2026 3:32 am CJH looks he lost a lot of weight. Nice drama.

Indira Mar 19 2026 9:00 pm This is so good. It's a warm drama. They also portray every family members situation in such a fine way. I usually skip unnecessary adds up roles, but I watch it and I skip no one in this series. It's a slow burn romance melodrama. I like the tiny hint of comedic scenes. Everything is wonderful. Maybe, it's because it's raining here and I feel like my life has been so flat and lonely that's why this drama just click for me these days.

Jia Mar 18 2026 6:01 pm chae jong hyeop serving looks and great acting here!!! & this drama is sooo good!!

HYJ Mar 16 2026 9:58 am This drama is honestly one of the best I have watched in more recent times. I vouch whole heartedly for people to watch this. It portrays life as bittersweet but reminds us to find the goodness and happiness in the more simpler of things. All characters within this show all have such depth and character and history which add to the storytelling. The slow unravel of the past is also something to look forward to with each new episode. The human interactions and familial dynamics is also very endearing, relatable yet melancholic with how life can just throw you lemons and curveballs, but sometimes you just need to find the right people or just be grounded by familial support to help you get through things. Cannot wait to see how the rest of the story unfolds with each of the characters and especially the main leads!

Sina Mar 14 2026 12:02 am This is definitely the Best Drama I've watched.Tye chemistry of Lee Sung Kyung and Chae Jong Hyeop is insane,such a good pairing. Watching Chae Jong Hyeop and Lee Sung Kyung really makes me want them to date so much. They deserve the Hottest couple Award of 2026

SungKyuungggh forevs Mar 01 2026 10:10 am At last. Any Sungkyung drama never disappoints. I really love the slow burn dramas like this one unlike other dramas, another gem on my drama list. Love the twist and turns. And as well as the other characters, I love to know their love endings as well. Kudos to the male lead as well, great chemistry with Sung kyung ♡♡♡

Miks Mar 01 2026 10:06 am The Male Lead is such a breath of fresh air. I’m falling for hiiiimmmm

Kdrama paksanim Feb 28 2026 10:37 pm I just my jun, ki hyun woo is part of the cast. His smile is wow.

Tabn Feb 28 2026 9:44 pm I love the way the plot twist. Hope for the happy ending for the FL. She would never lost anyone again

Star Feb 28 2026 3:22 pm Nice .. Highly recommended:)

HYJ Feb 27 2026 3:27 pm @Olya_1004 Yeah, honestly I was a bit lost even with the clues near the end, until I rewatched it a 2nd time and it really does click! But you were really on the money after watching only halfway!!! I think the boyfriend should be dead, but it would be an interesting but odd twist if he wasn't! After watching the 3rd episode now, this drama really has so much potential for being the best drama ever imo! They are both just chemistry-ing and the stories of each of their past being slowly unravelled is just great story telling. Definitely going to be an emotional rollercoaster with this one I think!

Olya_1004 Feb 25 2026 3:25 pm @HYJ it made more sense towards the end of the episode,I honestly made that comment halfway through it but something didn't add up for. I'm only now watching the 2nd one and I can't believe I was right ? I wouldn't be surprised if the bf is not dead or if he is it wasn't in the explosion. She received a call from his sister way too fast and no one will be calling family members while in an active incident scene,at least my thoughts on that. The drama so far is looking really promising and I like the twist on the usual tropes

Susan Feb 25 2026 6:54 am Love it and the idea behind it!!. Great.

Shen Feb 22 2026 1:39 pm Looking very promising and Lee sung kyung Looking very beautiful

Wow Feb 22 2026 1:04 pm My guess is FL has a crush to someone, lets say he is X. But X doesnt like FL so X give FL the ML contact. ML pretend that he is X. Then ML goes to USA, thus the first scene.

Emgee Feb 22 2026 11:02 am Oh my, this is beautiful!!! I love the first two episodes!!!!!

Mae ?? Feb 21 2026 4:30 pm The chemistry between the leads was undeniable; you could feel every emotion in their scenes together. It never felt forced it was raw, authentic, and beautifully portrayed.The series is off to a good start and is showing a lot of promise so far.

HYJ Feb 21 2026 3:04 pm @Olya_1004 OMG When I finished the first ep yesterday and saw your comment, it really made me think that you might be right since I was so confused as well! And then after watching the 2nd epsiode today, I had to say that I can't believe you guessed correctly! It makes a lot of sense after thinking about what you said as to why he knows everything but she doesn't know him exactly... I just find it so sad that the actual boyfriend was such a bad person to her... I love LSK and CJH together in this show so much!!! They really have good chemistry after watching the first 2 eps!

Dongju Feb 21 2026 5:55 am I'm not sure why the FL "forgot". But my assumptions why he ran to the lab is that he was pretending that he was still a student but he's no longer not, so because the FL expected him to be there, he ran like crazy.

But this is my initial assumption and Kdramas can be unexpected so it could be true that he's not the same guy. I think he's the real guy though because why would he have those memories? My mind just thought that maybe she hasn't seen his face before, but that also doesn't make sense.

Annaanna Feb 20 2026 8:42 pm Interesting! I think Sun Woo-chan isn't the boyfriend of Ha-ran 7yrs ago, I guess it's a different person. Anyway, I saw Yoon Park in this series, and I realized how I miss him and LSK from the series Flower of the Queen. Happy to see them work together again. Can't wait for more episodes to watch. Kudos!

Olya_1004 Feb 20 2026 11:26 am SPOILER if you haven't seen episode 1

Okay the drama literally came out today but I am making my predictions. ML is not actually the guy she was coming to meet at the start of the drama and that's why she doesn't know him. I think maybe it was his brother or friend because anytime she was calling him he never actually spoke to her and some of it looked like recordings instead of actual calls. Also, the name they keep saying at the start is Chan but he said is name is Woo Chan and he emphasized that. Maybe he was in love with her or just feels guilty. Also why would he be running to a lab when she told him she's coming unless it was to let the actual person know? That's just my guess so far,could be way off but it seems like it to me.

Moon Feb 20 2026 11:08 am I am confused . Did the FL lose her memory? was it the ML?

Dot Oct 21 2025 7:28 pm I cant wait too!!! LSK !!

Qwerty Oct 17 2025 10:25 pm LSK! I'm excited to see this!

rum Sep 28 2025 1:19 pm i cant wait!!!. Im rooting for the actors and the drama!!!
