Why doesn't he marry him and make the owner of the house?

Is there any legally binding marriage between men in SK? No, that's they can't get married. The only other way is through adoption, but idk how other people feel about that. *shrugs*

I think there's no time to fly into another and get married. He's in rush ...

I thought SK is liberal. Even if there is no law isn't it fictional they can show or write anything they want.
