I think this series is pretty good at the beginning. I like how ML starts to come out of his shell and blend in with his classmates. But when they begin college life, it goes downhill from there, at least for me. It feels like it doesn’t have a main plot anymore and just becomes a documentary about their college life. Even the friendship vibes are less prominent than during their high school days. Then, some random characters show up without adding any significance, like Gao Ting. He rarely appears, yet suddenly, it seems like he's the main antagonist without any background story.
