angst to kill you and heal you

A lot of guilt towards the loved one. Trying to prove one's humanity. Trying to prove yourself worthy of love. Obsession (non-abusive).

Lovers kept apart by death (reincarnation), murder of the loved one committed by the ml,  guilt, and misunderstanding. 

Love intensity = 10/10 (Both male leads are willing to kill and give up all including their lives for FL)

Lovers from opposite factions. ML responsible for the death of most of FL family. Supper possessive, obsessive, and abusive. 

Kept apart by memory loss and FL hatred for ML (later on).

Love (but let's be honest obsession) intensity = 10

True power couple.

Kept apart by misunderstanding, death(resurrected), opposite factions, family.

Love intensity = 7.5 - 8 Would be way higher if it only wasn't a censored romance :(. 

One destined to be evil. The other first fighting to kill him for the version of him that murdered her family then fighting to keep him from becoming the devil. Romance 8.5/10 unsatisfying ending. There is a brief arc of obsession from the male lead.

Kept apart mostly by ML's hidden identity. Extra angst comes from ML's father being the suspect in FL's father's murder.
Love intensity = 7 (rather healthy and cute romance. Blanaced in how they both care for each other. ML adorably clingy to the FL)

Connected through the murder of the ML father.  The "you will become a killer like me" vibes. ML can read minds.  FL is ML first love.

Kept apart: age ( ML younger but nothing romantic happens from the FL side until appropriate), memory loss ( if I remember right), circumstance caused by the antagonist 

Love intensity: 7 ( ML has a total puppy love towards the FL)

Ex-boss and employee situation. Ritch ML . 

Kept apart: Family, terminal illness of the FL.

Love intensity:  7.5 (willing to give up all for her)

FL Revenge on ML. ML Guilt. ML redemption arc.

Kept apart: Family, terminal illness of the ML, bad actions of the ML, FL revenge.

Love intensity: 6.5 - 7 ( The ML was willing to give up his happiness for the FL. But there wasn't that much focs on the romance more on the guilt. Plus the fl seemed to realise her love when it was too late.)
