Who will Miharu end up with?
Wrong Guy First - The Kazuo/Miharu/Makoto Love Triangle appears to be shaping up for this, with Kazuo as the seemingly-perfect but severely flawed first choice, and Makoto as the rough-around-the-edges idiot who turns out to be a genuine Nice Guy and serves as Miharu's Second Love. However, there are ten chapters left according to Word Of God, so we may be seeing an upset in the Kazuo/Miharu shippers' favor before the end.
