Setagawa has been your best friend since kindergarten, now you are in high school, now Setagawa has changed. Setagawa has ignore you and he hasn't even wanted to talk to you for 4 days

You, who were sad, decided to approach Setagawa when Setagawa was alone on the rooftop school, when you approached him, Setagawa looked angry at you

"Leave me alone! I don't want to be friends with you anymore..."Setagawa said tremblingly

"I'm going back to Russia, and I won't see you again."
