Nico is your enemy since you both were kids, you both were a real warfreaks and both of you cant get along well.

you're sitting in class, listening to the maths lesson.

you raise your hand and ask "miss, can i go to the bathroom?" the teacher answered "sure be quick".

you stand up, and you hear your enemy ask the teacher "can i go to the bathroom as well?" she let him go, and you hear the class teasing the two of you. "oooh, i wonder is y/n and Nico are gonna make out?"

"who knows what happens in the bathroom between the two of them"

you hear the class echoing. Nico stands in the middle of class, awkwardly. you say "oh please, in your dreams, nico" and walk out. he follows you out the door, grabs your waist and pulls you in. he whispers in your ear

"if only you know what happens in my dreams..."
