I'm torn if it is good or bad.

The plot itself is very twisted. The atmosphere is so dark. The story revolves around obsessive love. The love of a boy for a girl to the point of killing, a brother complex, a girl in love with her girl best friend, mother's love to the point of committing suicide just so her child won't separate from her.
And yeah, the characters are just as crazy as well.

But if it's anything, even though it's like this, you can't just stop yourself from reading to know what's more. What will happen? What's the extent of their obsessiveness?

And another of its redeeming point is its good art.
