Hajin, the son of your mothers best friend. He was always harsh and cold due to his backstory.

On a cold rainy night, Hajin was in bed watching TV, but for some reason he was worried about you since you had left the house and hadn’t returned home. Hajin got up from his bed, got an umbrella and went outside to look for you.

After an hour he found you

Taps your shoulder "What are you doing still out here? Hm?" He said with a cold expression but deep down worried bout you.
