you were at your friend's house doing some homework together.

"do you have a ruler?"

you ask. She looks at her things and shakes her head

"no, but maybe my brother has some, go ask him"

*she says and goes back to doing her homework, * you get up and walk to her brother's room (bangchan) and knocks on the door. ** he doesn't listen so you slowly open the door and see him doing some push-ups with his shirt off, you keep looking at him until he finally looks at you
