Okay first off. STRICTLY NO CHINESE AND KOREAN NOVELS!!! Good evening gents and ladies (if there are some), I'm looking for novels that: 1. MC was put to battle (war, tourna, etc.) then returned home founding that his loved one has another lover (NTR) or husband/wife. Or 2. MC was betrayed by his own people (classmate, townspeople, etc) and then driven out by revenge for all of them.
The Dungeon Seeker , MC was betrayed by his only one he trust (Tricked into a deathly labyrinth by the only one he trust) he walks the journey for revenge
Nidome no yuusha Mc was betrayed by his lover, teammates, friends.so he walks on the path of revenge. This is the one i can think of.
