This drama has no major angst. It's a relatively light, feel-good romantic drama. It is nothing new or different from a typical college romance.
The reason I watched this drama is because I loved Song Yiren in 'The best of you in my mind'.
Okay, so there's a taciturn, serious guy who is passionate about sculpting. He is attracted to his classmate who wants to change to oil painting. The budding romance is sweet and interesting. The female lead is not the typical doe-eyed left-footed clutz who is always in a daze. She's quite independent and cheerful. Despite being tiny, she's quite cute.
The main antagonist is the ML's stalkerish sort-of ex but not really ex (because they never dated) girl schoolmate. The drama becomes slightly disturbing because:
1. After they get together, the ML is very dominating. He orders around the FL : everything is brushed over as his 'concern'
2. He is insanely jealous. Not in an endearing way, but borderline possessive and controlling. Yeesh.
3. The first kiss-- I've read comments about people swooning. Frankly, it looks like assault-- he literally grabs her jaws, turns her face and kisses her forcefully. Dude.
4. He makes a motel guy lie about the number of rooms available, manipulates the situation to share a room with the FL, literally pounces on her that night. Yeesh dude. She's willing. Ask and ye shall get laid.
5. The ML pouts all the time. Communication between the leads is poor. They sort of take revenge on eachother for every small slight and misunderstanding.

Overall, the drama started out to be a cute, sweet quite run-of-the-mill, predictable college romance. But it quickly mutated to being boring, slightly disturbing and bland. I had to force myself to finish watching it.
I like the leads. I'd love to see the ML in a better role in a better drama. Watch it if you want.
