He raises her to be his ideal woman and perfect girlfriend, but in reality, this Rin is an AI that closely resembles the woman Junki has been secretly in love with. Thanks to Rin, Junki learns how to interact with women and eventually wins over the girl he has been pining for. However, Rin's AI suddenly vanishes without a trace... At some point, Rin begins to develop emotions 'I love you, goodbye.'
