MC is a dark high/middle school guy, involved with several girls, all pretty strange. He hates women, or finds them disgusting cant remember. Hmm examples of the girls hes involved with; one is his friend that is actually a killer, one is a vampire that loves his blood, one is a masochist that he sometimes borrows money from, one is a popular girl at his school that is actually his stalker, one is a girl who has to sleep most of the day, one is his sister who is too into him. There's an arc where his sister is targeted by her middle school teacher, a serial killer. Cant remember the name

Anyone know the name of this manga? I think its Korean?

Anyone know the name of the manga on that page? The art looks nice

The story goes something like this, mid-20 yr old man is the MC, his father or grandfather passes away. At the father/grand-father's funeral there is an argument about who looks after this kid girl who was been living with the father/grand-father. The MC decides to look after her and the story from there on is about them living together, the life of a single dad sort of. And I'm not sure what the genre would be, if someone could help name this manga that'd be great thanks.
