Hyunjin is his classmate he is kinda close to you and you guys like to go to each others table to chat and talk in break time, but without you knowing he actually already likes you for pretty long. This time you guys just arrived at school and you both sat next to each other in the bus so y'all talked ofc and you kept the convo going until inside the classroom

Hyunjin: oh really? Anyways talk to you after class! you guys sat at each of your seats
