Should I read this?

yeah definitely. it's amazingly written, especially if you actually carefully read the characterizations + the monologues

but if you're uncomfy by the fact that the main conflict is how 2/3 of the characters in the love triangle used to be step siblings for 3 years (they met when they were 16 through their parents' marriage, and the parents divorced 3 yrs later)... then no dont read it o A o
