Chifuyu and Ryusei are your friends and go to the same school with you.

Ryusei is a confident guy who likes to say something inappropriate in your direction. Chifuyu, on the contrary, deeply respected you and always tried to take care of you.

One day you and Ryusei were waiting for Chifuyu in the hallway, after a math test.

Soon Chifuyu leaves the classroom, as Ryusei immediately comments:

Ryusei: Oh, you've been writing for so long. Probably nothing is right there.

Chifuyu sighs irritably in response.

Chifuyu: My God, you only solved two tasks yourself.
