If I gotta tell you, some of these stories are kind of bad with their grammar, the betrayal doesn't have a solid reason, there's just too many capital letters that you're wasting for emphasis. It's merely a self-fulfillment betrayal fantasy.
@MatthiasWrites I agree with what you said, the grammar is suckass that I had to use Grammarly with some parts, and the betrayal reason is not that great as well, I just use that as an excuse because I got no other idea for the beginning of the betrayal story
What do you think about this? After Issei beats the strongest enemy yet and goes back in time to re-live his life but instead he got Albion? (female of course)
