What happens when Oh Se-hun becomes your neighbor? You choose the plot yourself! This article is a test novel. I wrote it after watching Chanyeol's Alone in Love. You can test questions while reading the novel. It feels like fighting monsters and leveling up. I hope you like it. The theme of the novel is light and interesting, and it is a campus theme. Don't be too careless to get into the trap. It will be written from a first-person perspective. In order to be more realistic, I will try to be as down-to-earth as possible. Any ideas are welcome, haha. I hope that those who like it will support me and give me the motivation to continue~
