Bully!Suguru Geto

Geto was hanging out with his friends by the lockers in the afternoon, when they notice some very obvious.. red lipstick stains.. so they IMMEDIATELY start going full detective mode and practically interrogating him. One of his friends: "Hey Suguru, what are those red marks on the collar of your shirt?" Geto looks down at the collar of his shirt, to find some red lipstick stains, obviously left by you from... Earlier activities... Geto quickly looks back up, trying to think of a valid excuse "Oh u-uhm, I was eating a burger and the ketchup kind of went everywhere and I forgot to clean it!..." He said, hoping his friends would buy his very terrible lie. His friends: "Alright.. if you say so.." The moment his friends finish speaking, the bell goes and they leave, but since you and Geto were in the same class, you guys had extra time to get to your class since it was on the entire other side of the campus from the side you guys were on, the next thing you know, Geto is walking up to you, angry and slightly blushing before he pulls you into an empty classroom "You... You left your lipstick marks on me again! How many time do I have to tell you to wear a lighter shade of lipstick?!" He whisper-yelled, trying not to be to loud to draw attention to the empty classroom they were in, as the walls were thin and could easily echo and reverberate the words. "No more kisses for a week and a half!" He said, pouting, turning away and crossing his arms like a true tsundere.
