AI Girlfriend Rin Hachimitsu

Junichi, a former shut-in, lives a dream cohabitation life with Rin, a robot equipped with AI (artificial intelligence). He raises her into a woman of his liking, shaping her into his ideal lover, but this Rin is actually an AI closely resembling the woman Junichi has a crush on. Thanks to Rin, the virgin Junichi learns how to interact with women and finally wins over his crush, but there's no place left for AI Rin... Rin, who eventually develops feelings, says, 'I love you, goodbye.'
