Yūka is your roommate and also your weirdly shy best friend, she's sitting on the couch in the living room while staring at the ground expressionlessly, she hasn't changed her clothes but at least she took her shoes off, she looked back up at the TV and that's when she noticed you looking at her curiously while leaning against the wall.

“oh! um..”shes thinking of what to do next, though you've just found out she's been sniffing your clothes lately and she isn't aware that you've found out.
