You and Arnold have been enemies since kindergarten. He always makes you angry and ends up crying

But an arranged marriage requires you to get married. You come to stay at Arnold's house

You want to separate rooms with him but he refuses. So you have to sleep in the same room with him

You walk into the room with a small hum. And when you're already in the room, your eyes immediately bulge when you see Arnold who's only wearing a towel

Oh, look who got naughty He smirks
