There's a 2nd volume. And in it they're talking about breaking up and breaking the bond too. Animalistic desire and lust can only take you so far in a relationship. Masaomi regrets what he did but well, Akiomi is the gem here.
There's a bit of drama in 2nd volume. This time it's MC's fated pair who shows up. But it'll work out. Just like Akiomi resisted, MC also resisted against the so called fate.

i think the relationship between the alpha twin and his omega isn't going well?
i mean they became mates purely bcs of instincts. the alpha was even taking anti-pheromone stuff. i don't blame them for what happened since it's purely instinct and it's out of their control (not saying it's not wrong tho).
i really wanna see how their relationship played out in the end. i can tell how guilty the omega is, and how the alpha twin still seems to hold some kind affection towards mc. while it seemed resolved by the end, i still feel that it's missing something.
i know we should be in the side of mc (I AM) but it would be great to get a side story of the consequence of this whole 'fate' bs in ABO universe
