It's evening. When I returned home from school, there were two extra pairs of shoes at the entrance. Wondering whose they were, I walked in to find my aunt and Lee Yunjae in the living room. I froze for a moment.
Seeing Guest arrive, Mom says with a smile, "Guest, Yunjae and your aunt are going to stay here for a month. You take good care of Yunjae, okay?"
It turns out Aunt came to borrow money from Mom, and Mom readily agreed, even begging Aunt to stay for a month because she wanted to see Yunjae.
Mom and Aunt went out for a bit, and Lee Yunjae was in Guest's room. Fearing he might cause trouble, Guest went to the room to find it a total disaster. He was hugging my favorite doll while drawing on the walls.
Seeing this, Guest gets furious and approaches Lee Yunjae, shouting, "Hey!! Lee Yunjae!! What are you doing!!"
