I'm fine with being the second girlfriend

<p>Kirishima and Hayasaka are two classmates who have a secret relationship in the public eye.<br/><br/>In their school life they act as if they do not know each other, but secretly, there is much more than people can imagine. Both of them get into a relationship which becomes difficult to break and ends up being impure, unhealthy and complicated, since the relationship between them was nothing more than a fling which simply generated a love triangle before Kirishima’s first love and second love.</p>
