Magda USA Nov 02 2025 9:05 pm This young man,Ong Seong Woo, is soooo good looking! He’s adorable! Handsome! And a very good actor! Very natural in his acting! As if it comes easy to him. Love him in Strong Girl Nam Soon! And really hoping he will be cast in many more series as the l ad with beautiful young, his age actress.

Jhanzenne Khai Capesos Aug 04 2025 8:05 pm I love Ong Seong Wu so much. I fell in love in him in Strong Girl Nam Soon and as a grade six student I seriously got obsessed with him that I keep on searching him on Google.

Bao moua Mar 26 2024 9:19 am I’m a big fan of Kang hee-sik he take my breath away when I first watch strong girl gang nam soon he is one of the greatest movie actors I hope he come for seasons 2 of gang nam soon. They made a very cute match i ship them as a couple ??

Rishab Mittal Jan 19 2024 7:53 am This is my idle and my dream to meet at once and collect his autograph

eugene Dec 25 2023 10:23 pm wow!! i last saw him in wanna one !! he good in acting in namsoon i suddenly saw him. i 100% reco strong girl nam soon for fun and chilly watch !!!

Frozie Dec 08 2023 7:33 am My gosh, this guy can act! Saw him first in Strong Girl and thought he did a great job, and now I'm going back to catch his debut (At Eighteen). Um yeah. Very different characters, both convincing. Facial expression, body, language, dialogue delivery--all of it just excellent, you really feel the emotions of the character. At first when I started watching Eighteen I was like, Kan-i-shik! But quickly I forgot about Mr. Police Inspector, because Choi Joon Woo is a completely different person.

I hope Ong Seong Wu has a very long and prosperous career ahead of him. There is nothing more enjoyable to a viewer (at least, this viewer) than to see actual ACTING in a drama or movie. I'm definitely looking forward to his future projects!

Favour Nov 30 2023 2:29 am I love his acting ?

Vindy Nov 21 2023 11:12 am I fell in love with Ong SeongWu in the drama NamSoon, his acting is very good, even in just one drama we can see his acting angry, sad, happy, jealous, in love, funny, he can be beautiful, handsome and basically Ong SeongWu's acting is extraordinary! ! I will wait for your next drama or film project, I support you! Ong fighting!!⁠♡

Coleen Nov 21 2023 11:06 am I enjoyed Ong Seongwu’s acting in Strony Girl Nam Soon. I laughed at his comedic scenes and was teary eyed when he cried because his superior died. I also feel the butterflies during his sweet scenes with Nam Soon. Oh. I also like his tandem with Geum Joo. Especially when he was Jamie Choi. I enjoyed also his scenes with the detective squad. All in all, he did a great job acting as Kang Hee Sik. Hoping to see more of him and his future projects.

NP Nov 21 2023 10:41 am Ong Seong Wu is a Real all rounder. Acting, singing, dancing etc He is good at everything. He is not only good looking but he also has a good mind and attitude too. So, that why he is my favorite actor(+artist) and my role model in real life. Can't wait to see him in new projects soon!!

Jasmine-booming system, TYtrack, TYtrack Aug 12 2019 1:13 am When I was watching Produce 101 and also Wanna One after that, he was the one who caught my attention the most. This multi talented guy with a face that makes you swoon will never seize to wow you. I don't think Korea is sleeping on him now, because of Pd 101, but do continue to support this HaWT bOi. (P.s., I could recognize that jawline anywhere oOF sorry I'm just kidding hehe:) )

Chenay Aug 11 2019 3:38 am so handsome, I love him so much. Great actor, great singer. !!! Please listening his MV on YouTube

mamichan Aug 10 2019 4:55 am Such an eye candy! He looks so cool in the current drama moment at eighteen, makes me forget that he is a funny clown member in produce 101, haha.. I can't resist his smile, his deep eyes everytime he look at soo bin. I used to call kang daniel my baby because i though he is the cutest, but then i found seung woo and i can't take my eyes off of him since then, even though i'm a mother of 2 kids hahaha.

Soo Bin's Jung Woo Aug 08 2019 1:32 am I knew the Korean group Wannaone and only knew Kang Daniel since I think he's more popular than the other members. But now gosh! I love Ong Seung Woo, his acting is surprisingly good given that it is his first time and it's a leading role. I love also his chemistry with Kim Hyang Gi. Jung Woo and Soo Bin are both cute and lovely couple. Wishing him more success in the future!

P.S He reminds me of Infinite's L in Moment at 18. I don't know why hahahah

Soo Bin's Jung Woo Aug 08 2019 1:24 am I knew the group Wannaone and only knew Kang Daniel since he was I think the most popular one of all members. I didn't bother the rest of the members but now! Gosh! I'm loving Ong Seung Woo now. He's acting in Moment at 18 is surprisingly good given that it's his first time and its a lead role not unlike other idols are just supporting characters (Reminds me of my UB Suzy Bae) I love his chemistry with Kim Hyang Gi, they are both a cute and lovely couple. Wishing him more success in the future.

P.S His style in drama kindly reminds me of Kim Myungsoo of Infinite. I see sometimes their resemblance or is it just only me?
