A high school girl, Utako, has an unusual 'love'. That is, she was attracted to cold attitudes and when someone dealt with her in a bothersome way!　She has no romantic feelings for him, but is always attracted to boys who behave in this way. She met Narumi by chance, who was always languid and had a slightly teasing way of saying things, and he was exactly her ideal ♡ In order to become friends with Narumi, she tried to get to know him, but...?

She's confessed 100 times, what happens on the 101st?
