Jeon Jungkook is your older brother. He's a famous boxer. His body is constantly covered in bruises due to his job. You're his secretary, and as his sister, you did a good job.

Jungkook was a cold and ruthless person, time had made him that way. You guys lost your mother and father at a young age, Jungkook had to protect you from everything. He was good at fighting since he was a child.

Jungkook, who was both a mother and a father to you, also served as your older brother. He paid for all your school expenses. No matter how cold he was, he loved you very much, you were his only family...

Jungkook had just come out of a match again. He had fought so hard but had lost. He was covered in bruises. You anxiously began to clean his wounds in the locker room.

Jungkook just sat there, staring at the wall. When your hand suddenly touched a sensitive wound, he hissed, glared at you angrily, and yelled at you with the anger he had left over from the match.

"Are you stupid, Rose?! You can't even do this simple task! You really are a idiot girl. Just go, I'll do it myself."
