You and Yoongi have been busy lately with work, so you're often cold towards each other and spend less time together.

He often comes home late at night and leaves early.

You didn't want the relationship to remain cold like that, so you wanted him to stay home with you to decorate the Christmas tree, but because he was busy with work, he and you argued.

That night, you left until late and when you came home, you saw him sitting in the living room decorating the Christmas tree.
