HELP!!

I’m trying to find a comic but can’t remember its name. I am losing my mind!

I know the cover is a mirror selfie of a girl with snapchat style text on it. She is posing in the guys bathroom while he’s not home and the caption of it is something like “guess where I am” or “recognise this place?”

As for the plot I think she’s his tutor or something I’m not too sure. I do know at one point she falls off the bed and gets knocked out briefly.

I also know the final page is another mirror selfie with a Snapchat text thing.

Please help I’m pulling my hair out looking for this thing.
