Yoshou Tokiwa

I, Mashiro Saeki, raised in a large family without any private space, finally got permission to live alone upon entering high school. Although it came with a condition: "Don't have inappropriate relationships with the opposite sex." And yet, just after saving my neighbor and classmate, the gyaru Arisa Amagi, from a problem, she's been trying to seduce me in every possible way!? There's no way I can resist this!
