Pretty good, not 100% sure about the NTR tag because the only witness is the daughter and she seems more traumatized then aroused about her father raping her friends.
At first I was wondering where the NTR tag was but I guess since the gangrape was actually a flash back and the male lead wasn't actually emotionally traumatized it's not needed. But overall it has a happy ending.
10 out of 10 would fap again.
5/5
