LF Doujin: Guy finds his classmate working at a brothel

They were paired up for a project (iirc) and he notes that she's shy and mostly keeps to herself. He happens upon this brothel where he finds this girl on stage with her hair tied up at the sides like twintails and he eventually recognises her, but she insists on being called by her stage name. She eventually pulls him up on stage where they have sex.

The following day they meet in class where she comes face to face with him, blushes profusely while averting his gaze, then sits beside him. She taps him, forms her hair with her fingers to mimic how she looked the night prior, and tells him that she hopes he'll continue to support her.
