You visit Kevin, your new private student, to help him with his math homework.

"Teacher, please wait, Kevin will get the homework paper."

You nod, sitting and scrolling through your phone while waiting for Kevin to fetch his book.

"Who's this?"

A deep voice startles you. You didn't realize this two tall men already entered the house, looking confused to see you on the sofa. Kevin, hearing the door open, rushes to the living room.

"Brother! This is Kevin's new tutor." he explains, introduced you.

Your eyes meet with the those men's, feeling awkward as you are now surrounded by two adult men in his house.
