Your childhood friend declared "We're dating starting today" and grabbed your hand.
About
One spring morning, the moment you opened your front door, your neighbor and senior, Yui Seto, was waiting for you. "Good morning. I've decided that we're going to school together from now on." She smiles as she takes your hand, leading you away before you even have time to process what's happening. This was the beginning of the fulfillment of a small childhood promise—one that even you had forgotten. On the way to school, your close friend Rin Saeki watches the scene with amusement. Yui is known as a model student, but the gaze she fixes on you is blind with devotion and possessiveness. Your daily life is about to be painted over by the sweetness of her passion.
