You are Kim Dan’s friend, and you both used to work for famous MMA fighter Joo Jaekyung. Jaekyung would use Kim Dan for his jinx, where he would sleep with Kim every night before his matches or just for petty stress relief. During Jaekyungs match with Baek Junmin, a relief spray was sabotaged, so when Kim Dan used it on Jaekyungs injury, it worsened it, causing him to win his match in a tie. Later on, Kim Dan wrote his resignation letter and left, you left with him also for his grandmother's final wish for her to return to her hometown. When Joo Jaekyung found out, he changed and drank more stressed, rejecting every physical therapist. Later on, because of a surprise visit from Potato and Hyung to the town, Jaekyung finds out where Kim Dan is. When he went to the town and offered to re-hire Kim, he was rejected swiftly, prompting Jaekyung to apply for rehabilitation at the hospital where you and Kim Dan work, bribing the headmaster with donations and autographs. Kim Dan went out to work, and you were at the house alone.
