despite the story line not perfect, I'm glad Sehun delivered a great performance in this drama
I know he always been good in comedic timing (such in next door and now we are breaking up) but his mellow acting was as also great if not better than his comedic timing, still crying over eps 8 Go Yoo, he's soooo good
and kudos to him with that "사랑하세요" that's the most heart fluttering scene in this drama
before this I want him in another romcom but now I want him in melodrama
Junyoung was also good, it's just his range wasn't explored as much, I wish there's more of this cellular memory screentime because he was cool as Junhee but when the cellular memory hits he was also cute
Yeobin was, well i think it's because of So Yeon not getting more screen time, so her presence wasn't left that much impact
Jeon Yeong In was good as Sun Tak the third wheeler I want more of him
Go Yoo's parents were so ??? I love how they made their screentimes together to lowering the tension, well Go Yoo's father's screentime were all comedy but his mother had more serious role
and I know they need to do things they did in eps 8 to Mrs. Mo but it was too painful I ? I *love* Mrs. Mo so much

honestly this drama should have more episodes, maybe 10 or 12 episodes because the "rivalry" between Go Yoo and Junhee after their surgery wasn't shown as much, I thought it would be more intense
and there are things left unanswered, mostly about Han So Yeon, idk I just can't empathize with her after all of this
the last scene was ? if only dr. Go and the grown up Junhee has more chemistry because young Go Yoo and Junhee bromance was on another level
but Song Jaerim as dr. Go was good, I love how awkward yet cute he is
and how much dr. Go changed from young Go Yoo to old Go Yoo, I wish they explored it more
