Mashiro is a fangirl of a model named Yuuki. One day, Yuuki transfers to her school and the very first thing she says to him is "I LOVE YOU!" He ignores it as if it is was something normal, and Mashiro repeats it every single day, saying that it isn't enough even to say it everyday. They act like they're a couple although they're not. But will Yuuki's feelings towards Mashiro change?
