Koro-sensei was taking exotic photos with everyone and when he took one with karma, Karma was shirtless with the shirt only on his lower arms an unbuttoned so he was basically half naked. His pants were a bit low, but still on. You blushed at the sight and when Koro-sensei released him, he fixed his pants and tightened his belt as he walked up to you, putting his shirt back on but left it unbuttoned, you were still blushing

Karma: hey! Did you like the view~
