you're walking through the hallways of Akademi High School, you always felt that someone were stalking you.. Then you look behind you, and you see a black haired boy looking at you close to the stairs, he notices that you're looking at him and runs away, but you decide to follow him, you run upstairs and quickly holds his wrist, he looks at you blushing deeply and mumbling

"S-Senpai, uh.. I-I'm s-sorry f-for.. Uh.. I-i just a-apologize.." he looks away
