I would have rated this even higher had the story not shifted tone in the second half.

What I didn't like:
- First half was good up until ep 16 I think, and then the editing became increasingly choppy (scenes' transitions not done seamlessly) and some issues were thrown in without being properly addressed or even being necessary (her friend, her mental condition, ML identity revelation to the public etc.).
- Drama felt more melodrama as first, but when the leads reunited, it was more romcom-y. What with the common CEO trope being introduced later.
- Too long epilogue to stretch the drama for more episodes. Would have worked better with less episode count, but that's an issue with most c-dramas.
- ML's behavior deviated a bit too much after the separation. I understand he got his sights and lifestyle change from a reclusive songwriter to a CEO, but the changes made were a bit jarring that I felt tad disconnected with his character. Mom also accepted the ML so easily after all that happened in the beginning. Had I not watched mother-daughter argument when she visited her, I'd have thought that she accepted him cos he was no longer blind and for his status hahaha.
- Love the songs and BGM, but a lot of times, they didn't fit the scenes.
- Her being a psychology graduate was not too relevant to the story.
- ML family relationship was not fully explored (tho I like that we were shown his relationship with his father remained quite distant despite reconciled when FL came over cos that seemed more believable, for me at least)
- Second couple was boring that I FF them a lot.

Might seem like a lot of dislikes, BUT, this is actually one of the few modern c-dramas that I enjoy quite a lot this year.
- No overdubbing.
- The acting. Almost everyone acted so well in this, even Evan Lin whose this was only his second acting project (but first being aired). I think he will benefit most from working in this drama and I look forward to his future projects. Wan Peng was great as always. She was very convincing in whatever the character's trying to sell that I didn't feel like she was acting.
- Leads got nice chemistry.
- Their relationship progressed naturally and believable. I totally get why they fell for each other.
- No evil second lead trying to come between them. Even their separation was not caused by anyone else but was personal issues that they needed to overcome themselves.
- Characters behaved like real people. Conversations were rational and relatable.
- We were shown what the characters feel, and not just told verbally. (I like the scene in the hospital when ML was trying to touch his father before he went into surgery, but retracted his hand upon contact, cos it was unfamiliar for him).
- Like I said before, love the music, when inserted properly.

Overall an enjoyable watch.
