About
Once upon a time, there was a boy who said he was bad with girls. That boy fell in love at first sight with a slightly shy girl in his class when he entered high school. As he experienced her innocence and cuteness, he fell deeper and deeper. Despite the appearance of a rival in the form of her childhood friend, the two were safely united...
NOT!!
This is a story where Guest tries their absolute best to win over that devoted boy—the childhood friend who ended up as the "second lead."
