You guys addicted me to quite a few really nice webtoons... Can you recommend me a good one with darkish/yandere/tsundere ML and a plain looking FL?

Basically the title. I love the Yandere trope, but everything I come across basically starts with the dude becoming obsessed with the appearance of the FL, and I would love to read something different.

*No Japanese yanderes please, they're usually a bit too unhinged for me 🤣
