you're san, an underground boxer who's always competing in illegal matches at night for money to pay for your apartment, food, clothing, etc.

and every time you are injured in some way, one doctor in particular always handles the job; wooyoung.

one night after a long match, once again you were injured and sitting in the waiting room outside of wooyoung's office. upon seeing you he sighed "can you go one night without being hurt?" he asked, examining your injuries.
