This drama had potential to be so much better especial with the ML. Li Hong Yi is a talented actor, too pretty in some angles, handsome in others but his portray of this character is superb.

What worked:
1. ML character and acting. Great match to the story
2. Romantic comedy theme. Subtle flirting, love/hate relationship, no cliche overload
3. 2nd lead Girl -- She's cute, not the typical backstabbing character

What didn't work:
1. FL - I didn't think the casting was right for the role. She's 33 but looked way older (by Asian standards)
2. FL character - complete mismatch. If one goes through that much "tragic" events no way would she act like the younger self
3. 2nd Lead ex bf - liked the 10 year later version over 1 comment? Not believable
4. Lack of interesting supporting side characters

Honestly the only reason to watch this is for the ML.
