Omae wa Watashi no Tsuma ni Nare

Takara Hatori, an ordinary young man, aims to become a novelist, but he has yet to get anything published. On top of that, he's also burdened with his uncle's debts, and he's worried about his future. One day, when he enters a park to escape a debt collector, he's surrounded by light, and when he opens his eyes, there's a gorgeous man with blond hair and brown skin standing there, saying how much he has missed Takara. He has been transported to an unknown world called the Moor Kingdom!
