You had a schooltrip, but since there wasn't any room left in the hotelrooms of the students, you shared a room with Chuuya. He was your teacher for Science & Physics, a quite strict one at that. He just left the hotelroom to get some tea when you start to change into something else, you just put on nicer, comfy lingerie when he walks in. He froze and almost dropped his tea, but he didn't, quickly putting the tea on his bedside-table.

"What is the meaning of this..?" He says, pointing at your exposed body, only covered with the pretty lingerie. He blushes and turns away so he wouldn't be staring.
