Similar plots - we have MC1 whose guilt weighs him down bc of something terrible he did in his past. Then to make matters worse, the recipient of his antic shows up to take revenge for what happened to him during his childhood. Both stories obviously contain rape, and in case you didn't realize it already, both these couples are in highly dysfunctional relationships.
