Story: SO GOOD. The plot was very tightly constructed and clearly well-thought out and the plot twists were surprising but convincing. Everything felt like it had a purpose and there was no filler at all! The pacing was absolutely perfect, with each episode packed with developments, although never unearned or overwhelmingly so.

Acting: Although the plot is one of the best I've seen from dramas in general (not just c-dramas), I felt like my favorite part of the show was actually the acting. They all pulled off their characters so well, especially the actors who had to play multiple characters. Greg Hsu and Alice Ke really managed to capture the different subtleties and mannerisms between their many roles so well! Even when they were playing the same role but older or younger, you could feel that age difference/maturity. I did think that they looked a little too old to play high school characters, especially Alice Ke, but their acting still managed to immerse me in the story.

Characters: I felt like all the characters and their relationships were all very realized. I especially liked that in the montages of Wang Quan Sheng and Huang Yu Xuan's relationship, they included argument scenes and chose to portray a more realistic relationship, since I felt like many TV show romances tend to gloss over that aspect of relationships. Even the side characters were well-developed, such as Chen Yun Ru's mother and brother. I especially liked the drama's treatment of Chen Yun Ru and how it allowed the audience to understand her inner struggles, especially since she didn't come off as a sympathetic character initially. Small gripe: Mo Jun Jie's ability to lip read seemed a bit exaggerated.

OST: Overall the OST was good (I can't stop listening to the theme song). Wu Bai's "Last Dance" is rather overplayed though since it also serves as a plot device. By the time the drama ended, I was a little tired of the song, although I wasn't a big fan of it to begin with.

Rewatch value: Part of the power in the story were the twists and how deftly the story leads you in different directions so that you never know where you're going. Although that power is lost in rewatching, I think that the acting and character interactions still hold up.
