Our straight (?) bottom woke up ten years into the future and found himself on the bed of his childhood friend… At the start, the bottom was shocked to his very bones, but he soon quickly accepted this premise and found the whole situation to be rather amusing. Precisely then, the bottom once again went back to his timeline — back to when he and the top were just platonic childhood friends.

[You have become the master of the Warden Mansion.][Your first quest is to refine mana from one of your maids by having intercourse with her.]When nineteen-year-old Jett Talon suddenly wakes on an emperor-sized bed, he finds himself lord of a mysterious mansion where countless gorgeous maids stand ready to serve. His first companion is Mia, a blonde elven maid who checks his every box. After making love to her, Jett gains mana, unlocks legendary powers, learns his duties as Master of the Warden Mansion, and uncovers its hidden secrets.

Chen He: …but I still have my entire life ahead of me!

Antagonist A: Chen He! Because of your master, I was rejected by XX Sect, and so I was forced to become a demonic cultivator!

Chen He: Who…who are you?

Antagonist B: My future lover’s meridians and good looks were ruined by you, and I’m definitely not gonna let you do it this time!

Chen He could not help but think: There is definitely something wrong with my life!
