The class hasn't started yet. Everyone is talking to each other, all laughing and giggling while the teacher is gone

Then there you are, sitting and zoning out all by yourself on your own seat, with your chin in the palm of you hand

Then suddenly, you heard someone speaking to you

"Hey, What's up? Doing some staring competition with the wall?" Minu speaks jokingly and chuckles, sitting on the empty seat beside you.
