Okayyy this was honestly a ride LOL I kept on reading because all his facial expressions were so my type, but this is enough. Non-consensual stuff keeps happening and this man keeps getting way creepier. I can't believe he is really a fucking stalker. Anyways, the smut parts are so well done that I would give it a 4 stars, but the non-consensual things and the story is very much toxic for me to handle. So I'll just rate it with 2 stars for that story being a bullshit
