My Girlfriend's Boyfriend (我女朋友的男朋友)

Storyline

A Zhai is a typical otaku who is obsessively in love with the most beautiful girl in school, Pei Ni, but he lacks the courage and social skills to do anything about it. When he discovers a technology that brings him a robot companion from the future, he accidentally programs the robot to model Pei Ni’s ideal boyfriend, instead of programming it to be Pei Ni herself. Now stuck with a male robot companion, A Zhai manages to reorder a female robot and customizes it to be his Pei Ni. But things get complicated when the robot Pei Ni falls in love with the male robot, instead of A Zhai, and the three live together in a hopeless love triangle.
