When I looked at the raws I thought this manga was going to be some intense pervy shit like
Kaguhara's Fetish Notebook with the POV just analyzing the pretty girl's body fluids (saliva, sweat, etc), but the MC just has germophobia. I don't speak nihongo so joke's on me.
Btw, either she caught on her classmate's phobia or has a massive crush on MC, the other one knows EXACTLY what she's doing. That Keikaku face doesn't fool anyone.
