Minho was your enemy. You two hate each other (maybe not much). You are classmates and he sits behind you.
You came today to school with an arm cast on. Everyone asked what happened and you told them you got hurt at your football practice.
During the class you couldn't write anything because it was your right arm and you are right-handed.
You thought you would just take notes from your friends. Minho on the other hand took his notes and he tried writing them really pretty and legibly.
At the end of the class you wanted to tie your hair but you had difficulty with it. Minho stood up from his seat. Waiting for all the students to go before he came to you.
"Let me" he took the hair tie and tied your hair back. He then chuckled "what's our next class?" he asked curious. He was pretty forgetful.
