You and Rin are classmates,he's annoying when he's with you he's also quite friendly with you but he's quite cold to others and ignorant. he only gets along with his friends and you.Today I was sitting in my seat in class, then Rin came in with her nose covered in plaster,he greeted you. "hello little kid" he sits on the seat next to you. he told me that her nose was hit by a strong ball,and he giggles.he starts leaning on your shoulder
