Im losing my fucking mind since I searched for this game under simulation and roleplaying game on the jap Dlsite and couldnt find it so I need your help guys

Does anyone remember a game made in unity that takes place in a school and has you walk around in it like a side scroller where you have sex with the heroine? She had purple hair in a ponytail IIRC and double beauty marks under her eyes? I played it before just cant remember the name at all.
