その花びらにくちづけを　あなたを好きな幸せ

Reo fails her classes and Mai helps her to pass. To reward Reo for passing her quiz, Mai agrees to go on a date with Reo. One day during class, Reo is called to the school office. She returns acting strangely. After a lot of worrying and probing, Mai still does not know what has happened. This results in a huge fight between Reo and Mai, because Mai feels that Reo does not trust in her enough to share her problems… They eventually make up and ends in love.
