Nanaka is a school idol. She is the lead singer of the school band formed with Koko and Wataru. She prefers the "haptic" kind of communication, taking the hand of a person with whom she talks. Doing so, she confuses guys and makes the enemies among the girls. Of course, this girl, as well as others, could not avoid the fate of falling in love with Yoshiyuki. And Nanaka knows, that Koko, her best friend, has the same feelings for him. Friendship, love, hate...
