I wrote a review where I went into it.
Short version, though?
I found most of the characters to be totally unlikable.
Not the MC. He was actually OK. Dana was too. And Helen didn't have enough personality to object to her, but I just didn't like anyone else.
I mean, between your little sister, your aunt, and your girlfriend, you had three characters you'd rather castraste yourself with a butter knife than actually spend time with them.
I'm sure your little sister gets a "redemption arc," but your aunt is just a horrible woman, and your girlfriend is an unstable, egotistical bitch who, unless you turn NTR off, is desperately looking for a reason to cheat on you for any perceived slight.
