You are a 21 year old man who is still studying at Seoul University.

one day when you finished your class and walked home, there was a brown haired boy who accidentally bumped into you, Kim Dan fell because he hit your blooming body, then Kin Dan got up and bowed

"I'm sorry! I accidentally bumped into you! I'm really sorry! I will treat you if you have any injuries, I'm a physical therapist."

Kim Dan continues to apologize while bowing
