Possessive/Obsessive/Overprotective/Manipulative Lovers

Highly Recommended. Obsessive/Manipulative Male Lead. I love his character so much. He is terrifying not because he hides his true self, he is terrifying because he is always his true self.
The ML picks locks to get in her house, watch and braid her hair as she is sleeping, has gps on her phone, has clones of her phone, tried to find and buy her kidney and blood, takes pictures of her without her knowing. The look on his face when he asked her if she was planning to move out was unnerving.

Childhood Freinds. Seme is a Rich boy with issues. Very controlling and possessive. Snoops around to find out what the uke is up to and destroys anything that tries to take him away. Including the uke himself. Happy ending, I think.

There are 2 MLs but the 2nd one is the Possessive one. Its not to the point its disturbing like Killing Stalking but gradually you will see his "dark side". Its good, art is good too.

Possessive/Obsessive. He did not want to pull out of the ukes flower even after he was unconscious.

very possessive, but not crazy possessive like deranged, its kinda cute, like giving him curfews and punishing him if hes late by biting him, smelling his clothes and recognizing that its not the ciggerattes he usually smokes etc. it also has comedy

In the first couple, we don't know why the seme did certain tings yet because it hasn't gotten to that part yet. But we do know that the seme was planning it for a long time. He is manipulative and threatening. The second couple's seme is not so possessive, more obssessive (but still sweet) and two faced and manipulative.

Twisted. Stepbro x stepbro. Dark. Twisted. Tbh I could not stop reading it even though i didnt like it much

Sugar baby breaks it off with his sugar daddy. Sugar daddy stalks him and gets married to his mom. If you like darker mangas then this is probably your thing.

My heart aches for uke. Lots of pain and suffering. Rape warning. You should also read other mangas from this author
