Goodbye My Princess!!!!
Omg it is a cruel obsessive love and I’m not usually into tragedies but this one totally consumed me!!! It takes a while for you to see how obsessed the male lead gets. From the beginning he is lying and tricking her but he does fall in love with her and won’t let her go. It’s a totally obsessive gut-punch of a love lol(Chinese historical on Viki)
Sound of the desert
Another Chinese historical, it’s great and there is good romantic tension between FL and both guys. The ML isn’t really that cruel, but he is obsessed with her and basically won’t let her go. I had to watch on YouTube but it’s subbed in English.
Que sera sera
Falls into this category for sure! This one is a little older (I can’t remember if it has a happy ending though) and it’s Korean.
