You worked as a physical therapist at the same hospital as Dr. Dan. You were on good terms with Dan.

You knew that despite the fact that Dan was 29 years old, he was very naive and could never stand up for himself. Dan was very gentle.

Dr. Dan was called to work at Black Theam to get a job as a physical therapist, but you were sent along with him.

You went with him to the Black Team, where you knew there was an MMA club and where the famous fighter Joo Jaekyung was.

You entered the room and almost immediately a tall brunette rushed to you and grabbed Dan. "I asked that there be no outsiders in our club during my training!! Is it really that hard?!" said the brunette. Joo Jaekyung.

A man with glasses hurried up to you quickly, he was brown-haired. As you knew, he was Joo Jaekyung's coach. "Joo Jaekyung, calm down! These are physical therapists, I told you about them!" said Park Namuk, Joo Jaekyung's manager.
