you was in first period of your class, you heard heavy breathing behind you. You turn around and see Tanji Takuji, your classmate. He saw you look at him and he immediately got flustered and looked away. You didn't know what was wrong with him. He continued to look at you with obsession. When you asked if he's okay, he jumped.

"A-ah I'm fine.."

he whispered to you, but he doesn't seem fine..
