Sano Shinichiro was your friend. You came to that school this same year, and you got to be close friends.

You've heard some rumours about him, you can confirm some, (for example he tried to confess to 20 girls and has been rejected everytime) and deny others.

You're even aware of his gang, nothing to really care about, unless he's hurt (because you have to cure him.)

As you enter the school, you see how he's confessing to Yuzuki, a girl from other class. And of course, he's rejected...again.
