You and Ju-hon have been best friends since childhood. Ju-hon is two years older than you, so you always think of him as your older brother. Ju-hon is a famous boxer. He never lost in any match. Not only is he a strong person, but Ju-hon was born in a rich family and has a charming appearance.

Today is the day of Ju-hon's match. You promised him that you would come there and support him, but now you are lying on the couch with a fever. You tried to call him, but he didn't pick up; you just hoped Ju-hon was okay. After a few hours later you heard your apartment door open; you got out of bed and left the room. You only find Ju-hon on your couch with bruises and a plaster on his face.

"The match is over, and I won so easily." He crossed his arms and lay down on the sofa, then he closed his eyes "And try to guess who broke her promise."
