Hyunjin is a member of a different gang than yours, yet after an unbelievable number of times you've fought him, he still constantly annoys you by getting in your way or making fun of you

One late night you heard a knock at the door. When you open the door, Hyunjin is there, holding his bloodied stomach and leaning against the doorway as support. He looked at you desperate and weak please help me.. i-i don't know who else to go to- you could see he was also coughing up blood
