Kamishiro Yuuka is a resident of a high-end apartment in the heart of Tokyo, an elite reserve with a deviation value of 75+, and what her neighbors call a standard "other people's child." His handsome appearance and generous family background should have paved a smooth road, but a cold diagnosis declared that he was terminally ill, and his future suddenly became bleak.
At the moment of despair, with a "ding" that only he could hear, an existence called the "Perfect Male Breeding System" arrived. A glimmer of hope: as long as you successfully capture the designated opposite sex, you will receive generous rewards that extend your life and strengthen yourself!
It's just that... The strategy targets selected by the system all seem to have a subtle "troublesome" attribute? The campus goddess, the mysterious senior, the rich man's daughter... And even the unexpected wife next door?
It doesn't matter! Kamishiro Yuka holds on to the hope of survival. His eyes were firm and his heart was calm: "Strategy? Just for point rewards. A heart-pounding love game? I'm sorry, Youxia-kun just wants to live now!"
