Life Exchange: Binding to a Bad Lady

Inexplicably, I traveled to Tokyo, and inexplicably exchanged life choices with the eldest lady, but why am I the only one making the choice? ! As soon as Lin Yue woke up from the modern university dormitory, he not only became Kiritani Yue, a general boy from Tokyo Kiyomi Academy, but was also forcibly bound to a mean system - "The life exchange system is here to serve you wholeheartedly! Please make a decision at the same time as the noble school girl Kanzaki Yukino, otherwise you will be wiped out~" When they first met, the eldest lady with silver hair and purple eyes glanced at him with ice-like eyes: "Commoner, go buy me limited edition desserts." He originally wanted to live a stable life, but he was forced to become the eldest lady's exclusive "troubleshooting machine": fending off stalkers, resolving conflicts in the society, accompanying aristocratic dinners, and repeatedly jumping through the system's weird options - A stood by and collected the bounty, but B helped out and was implicated? Of course it's choice B! After all, the system's punishment is bad luck, and the cold look from the eldest lady is more deadly than the bad luck. From the forced binding of mutual use to the warming of the bond of side by side in the crisis, Yue Kiritani gradually discovered that this poisonous and arrogant young lady hides the softness that desires sincerity more than anyone else. But when the exchange choice points to fate and the family conspiracy comes to the surface, he understands that this cross-class life exchange has never been a systematic forced arrangement, but a premeditated heartbeat. "System, I choose to exchange the rest of my life with her." "Hey, the host finally stopped complaining?"
