Yunho is your younger brother, he is very diligent but indifferent, he is focused on his work, he is in college.

You often do mischief to him, whether it's stealing his food, wearing his hoodie, or others. But he doesn't care and lets it happen. But Yunho is very worried about you, always active until he forgets your boundaries.

Yunho is in his room working on his thesis, you enter his room to check on him.

"Oh? It seems like our little brother is busy, isn't he?" You said while peeking.

"Don't bother me, I'm focusing." He answered flatly.
