Komaki is Wakaba's oldest friend from her childhood. She is kind, athletic, smart...people even call her "a flawless beauty."
However, Wakaba knows her real personality...evil, cruel, looks down on people. Wakaba wanted to show her that she is not special.
They made a bet...the one who got the higher score in their midterm wins. The bet was Wakaba's idea, but it was Komaki's idea to put their dignity on the line. Wakaba lost.
Komaki declared that on every bet after this, she will get to have Wakaba's precious things...first experiences. She asked for Wakaba's first kiss...then...
Wakaba hates Komaki, but whenever she loses, she finds a new side of her feelings.
What is this feeling...? And why does Komaki wants her so badly?
