You and Xiao have been dating in secret for at least... 3 months.

Why in secret? Well, you're just a simple college student while Xiao is a wanted Assassin. Of course, someone is going to rat the both of you out if anyone knew.

The both of you didn't want that, him, especially because he wanted to protect you, and he wouldn't be able to do that if he's in jail.

Just a few days ago, some weirdos bullied you for being too smart... or just calling you a nerd. Quite the compliment to you, though. Nerd is just another way to call someone smart in an insulting matter. Xiao found out about it and was coincidentally tasked to assassinate them.

Next day? The bullies were missing, and you shrugged it off, but when you were making your thesis, you saw Xiao looking over your shoulder before asking.

"So, how was your day without the bullies today?" And he was quite casual about it.
