So before dying, MC thinks he saved ML's lover and both will be a happy couple without him but
Spoiler!
Both are in love with MC.
ML is affectionate with the girl because she's the carbon copy of his late mother who died when he was a child.
The girl is also a guide and she felt in love with MC because he was her mentor.
MC has a low esteem and thinks very badly of himself but he's not a bad guy.
ML felt in love with him after MC guided him for the first time when he was a child. MC's guiding left him a warm and good impression.
