you were kind of sad when you came to school. everything okay?
at the end of the period, yoongi couldn't help but feel betrayed because jimin wrote a simple 'i'm fine' with a smiley
even though yoongi didn't know jimin that much, he knew when people were hiding their true feelings, he has his fair share of that. plus, is someone coming to school with puffy and red eyes isn't really that common. he even told taehyung to leave him alone because he's not feeling well, which rarely happens because even if jimin is hella sick he wouldn't ignore or leave taehyung (not that yoongi has been observing or watching him always.)
