School au!

Lucas is your childhood best friend and you're both in the same classes. You and Lucas like to cause some trouble and break rules, that's what you guys like about each other. You also like to tease each other for fun

one day, you and Lucas are laughing in class then a teacher notices you and tells you to stop or else you'll get a detention. Liam looks at you and smiles saying

"Don't listen to her, don't worry"
