First, this drama suffered with too many episodes. If you're going to make a drama with no side stories, second and third leads to create conflict so the main couple can grow stronger, etc. Then you have to cut the episodes. It becomes extremely boring to watch half of a drama of nothing but mindless fluff. This would have been better with 14-16 episodes like most K-dramas. 25 was too much. You Are My Glory also suffered from this. Too much fluff and not real story telling.

Anyway, this drama is about a 14 year old crushing on her older brother's roommate. Nothing original really. We've all been there. The thing I didn't like about this whole drama was that it was FL personality trait at some point.

If you also hate the naive childish female to mature woman trope, you'll really hate it here because she never got to the mature part. Everyone said as soon as she got to university, she would mature, but it never happened. ZLS really put the baby uwu talking on thick in this drama. If you are around real life teenagers, you know they do not act like this.

Then there is the repeated phrase "I'm not a kid anymore." or "I'm an adult now." I don't know if she was trying to convince ML or herself. But for a supposed adult, she didn't understand simple stuff like him having a real grown up job and that having to come first instead of a date.

At one point, something breaks in the game. Not just any game. It's the most popular game in China in this drama. Anyway, something goes wrong and he has to stay at the office and work on it because you know, that's his job. Instead of understanding this like an adult, she pouts and gets all sad and questions if he likes her. Not only that, her roommates also jump on that train instead of saying "You know, he's a grown man with a job and actual responsibilities. Calm down and have a snack."

I also didn't like miss "I'm an adult" playing games after he confessed. Young women of the world, do not try this in real life. It backfires every single time. You don't need to test men of their love like a soap opera.

The most realistic thing in the drama was the parent's concern and brother's reaction to finding out they were together. Even that was solved quickly.

All in all, it's just another teen love story with a male lead written by a woman for women. Turn off your mind to watch this if you're older than 20.
