Their bodies touch under the sheets. ...Saya is always alone because she goes straight to the nurse's office when she gets to school. One day, Mutsumi, the reason why she stays there all day, barges in. He slips into the bed she's sleeping in, telling her to help him hide from the teacher who's chasing him, and kisses her to keep her mouth shut. She tries to throw him out but he says he's going to help her study from now on...... He's always been controlling, selfish and mean...... so why is he being nice to her now...?
