First of all, i'm gonna tell you all that i am not a fan of highschool/college drama. I dropped many youth drama, such as love 020, Go Go Squid, A Love So Beautiful, etc. So everytime i see people recommends this drama i was like 'meh'.
BUT--- after going through 'trial and error' finding my perfect drama, i decided to jump into this one, without no expectation at all.

Plot
The plot was superb ! As a non-fan of youth drama, i really like how they put the snippets from their future life in early episodes. It made me stay thoroughout the early plot of their highschool life, which is sometimes a little bit boring for me. Plus, knowing they're gonna ended up together save me from the pain of suspense when watching a drama.
The puppy love story in highschool was okay, but the only thing that really stands out for me is the FL family's dynamic. It's the kind of family that everyone hopes for, isn't it ? Being poor is suck, but having people that always stick with you no matter what circumstances is a real blessed in life.
The twins dynamic is also great. I like how they hug each other giving support, especially when the 'bad news' happens and the FL just automatically clung to her brother. It makes me really miss my brother :')

Acting/cast
I gotta admit that i'm not a big fan of Yan Mo at first. The poker face annoys me but then i realized it's just his character. In the latter episodes his expression grows and you can see how his lips curled slightly or how his eyes twitch when he's jealous. Other than him, i have no complaints about other casts. They act pretty well ! Especially Janice Wu ofc.

Music
The soundtracks are good and well placed

Minus
The brother's plot arc near the end is a bit draggy for me. So many misunderstanding and miscommunication ! I just watched it 1.25x faster lol
