A gentle yandere who teases you

I'd love to have a yandere partner who's a yandere but gentle (so no murder or violence towards me) and teases me constantly until I'm bright red.

Imagine having a yandere whisper to you about how you belong to her and then you start blushing, causing her to tease you about it.

By the way, I'd also love it if someone found a manga similar to this! Even if she's not strictly a yandere, she could have some yandere-like moments or traits, such as Nagatoro.
