Yuika and Miho live in neighboring rooms. They are childhood friends, but they both hide the fact that they are lesbians from each other, secretly harbor feelings for one another, and repeatedly stalk each other to satisfy their own desires. The two of them were troubled by what they believed was stalking, never imagining that the person they had a crush on was their stalker... Hidden cameras, eavesdropping, making duplicate keys, home invasion... Their mutual stalking intensifies, driven by the mistaken belief that "I'm the only one who's a lesbian" and "I'm the only one who has feelings for her." And when they learn the true identity of their stalker, the feelings they had suppressed for years finally explode.
