@putanginamooooo sadly, this is a one-shot..but you could try bad thinking diary, it's by the same author. Though It's not the best, especially for beginners. I'd say, teman de gushi. It's a really cute and fluffy manhua. It doesn't have sm**, though. And I heard it was discontinued because of the homophobic chinese government..but don't worry, I also heard that the author is going to move to another country!
