Yoshimatsu Hotaka is the president of the manga club and is always diligent with his school life and club activities, but even though he looks like a regular honor student in reality we have that there is something really odd with him; he has this bitter ~ heavy ~ melancholic look and is almost always looking at Awaya Nika, the beautiful, bright, radiant, super cheerful swimming club's female ace. Why does Hotaka acts all bitter like that? And what will become of him as the sports teacher orders him to have at least "one secret swimming class lesson" where no one is supposed to be looking, whereas he normally skips class activities due to personal matters?
