I Took In a Monk, But He's Strange (Revised)

Originally titled The Prince-Raising Handbook Luo Chuan, who transmigrated as a merchant, adopted an untonsured monk. He thought raising the boy to adulthood was the sole purpose of his transmigration, but unexpectedly, the monk was reborn and had an extraordinary identity. Chen Zhan had carefully planned his every move. On the night he was made a prince, he pinned Luo Chuan, the merchant who had treated him as a catamite in his previous life, beneath him. "At first, I only wanted revenge, but now I've truly fallen in love with you. Whoever you are, you're mine now." Younger reborn seme, wise transmigrated uke. They're both dark to the core. Uke-focused, with two strong leads. Content warnings: No childbirth. Lots of sweet romance for both of them, with some angst to drive the erotic scenes, plus military-tent play. Happy ending.
