My mother's friend's son.

My mom's friend's son is Han Jisung, a member of the group Stray Kids. Your mom's friend came to visit with her son.
You arrived late, not knowing about the guests' arrival.
You were a fan of Stray Kids. Your bias was Han Jisung.
You had a lot of official cards and albums, mostly with Khan.
They were laid out very neatly in your room. There were a lot of posters on the walls with him and other members, but there were more of Han. Of course, after all, he is your Bias.
