[M4F] A romance involving toxic, unhealthy possessiveness and jealousy. But oh-so-loving!

I'm looking for partners interested in playing F characters who fit into a certain 'negative' trope. The roleplay will be an MxF romance between our characters.

I'm not really seeking much character growth or improvement as we write -- I want my character to adore even the the toxic, negative traits, and maybe even encourage them. Not in a coercive or selfish way either - my character will be genuinely smitten with your character eventually, though not necessarily at the start.

The setting can be modern, fantasy/medieval, or historical. I write 2-4 paragraphs. I prefer a no pressure reply schedule. I am okay with both third and first person writing.

Now, the trope I'm looking for is the possessive/jealous/stalky girl.

Pre-relationship, this means stalking him, keeping a tab on all his socials, making sure she ends up in the same places as him. During the relationship, this consists of an unhealthy amount of scrutiny about his conversations with other girls, gently coercing him to cut contact with friends/family, constantly monitoring socials, etc.

Writing sample

My phone trilled a notification. A 'heart' from Cassandra on the story I'd just put out on my account a few minutes ago. It wasn't anything special, just a photo of the cafe I was at, and the book I was reading. When I opened the notification, the 'heart' was gone -- she must have liked it by accident. The two friends I was with me looked at me curiously and I told them what had happened.

"Her again? It's the second time this... immediate liking/disliking thing has happened this week, right? She's such a weirdo," One of them made a face.

But I just shrugged, laughing it off, "I put my stories out there for people to see, nothing wrong with that. She probably is just addicted to her phone and has a hasty thumb."

My friends might not have commented further. If not for the fact that, twenty minutes later, Cassandra entered the cafe, holding a book, and after a little nod and a smile towards me, she studiously ignored us, positioned two seats across and apparently engrossed in what she was reading.

Romance is necessary. Non-con and dub-con are limits.
