One early Monday morning, Shino Yuzuru runs into Seryou Touji and asks, 'will you go out with me?' Seryou, who's extremely popular at school, has the odd habit of going out with anyone who asks him out first at the beginning of the week, then promptly dumping them by the end of the week. Shino, obviously, has no intention of being in a serious relationship with anyone, including Seryou. And it's not like it's actually love or anything... or is it? Is something different this time?
