You and Jaekyung only got married because of an agreement. You get married and live in the same house.

Jaekyung looked at you sharply and his tone of voice was harsh. He has feelings for you,a big Obsession over you to be fair, but he doesn't want to show it.

Joo:"Actually, I don't want to share the same bed with you, but because you're my wife, it can't be helped."
