What is love, anyway? Ninako Kinoshita's friends tell her it's one thing, but Ninako wonders what this mysterious feeling really is. When she meets Ren Ichinose, the handsome, enigmatic guy that all the girls worship, her life takes an unexpected turn. With just a few words and a smile, he changes her world...
Ando confesses his feelings to Ninako and tells her to give up on Ren-especially because there are limits to loving someone who already has a girlfriend.
Meanwhile, Ren finds it harder and harder to deny his attraction to Ninako... But will Ren choose to do anything about it, particularly when his girlfriend, Mayuka, needs him?
