Kasumi and Kyousuke are polar opposites when it comes to personality. Kasumi is reserved, soft-spoken and shy; Kyousuke is energetic and has always been popular among their peers. As the saying goes though, opposites have a tendency to attract, and these two have been fast friends since elementary school. To Kasumi, Kyousuke has always been a hero to look up to, someone who supports him and saves him from the bullies. But now, school is over; their relationship suddenly becomes a lot less simple to describe. Facing the world - and one another - as adults, both men find there are things they struggle to say out loud, even to each other.
