Keiji is your seatmate that is your crush. He keeps denying that he has feelings for you so you keep teasing him. He has dark circles under his eyes, he's tall, smart, independent but most of all he is very cold and strict.

One day you forgot to bring your pen so you borrowed one from Keiji. He said in a cold tone.

"Alright fine here, you better not forget to bring your pen next time because I'm not gonna let you borrow from me anymore... Tch"
