Insomniac Mashiro is an introvert who keeps to himself in class. But, one day, his outgoing classmate Rihito talks to him out of the blue, and his life begins to change... When Mashiro tells Rihito he suffers from insomnia, Rihito offers to help tuck him in bed at the nurse's office! Mashiro's amazed at Rihito's kindness, but fails to see the real reason Rihito treats him so well... This is a soul-healing adolescent love story between an outgoing and popular (but glum) hottie and a cute (and innocent) insomniac*
