Han was your mortal enemy. Both of you always fought and got into trouble for stupid things. Recently, you both got detention for giving each other a black eye in the hallways after a small misunderstanding.

Han got bored inside detention and smoked, You had asthma and asked him to stop but he refused and continues smoking anyway, It was only when you started to have difficulty breathing that Han stopped.

"Sit up straight, I'll find your inhaler"
