Welp...The smartest and most logical solution for MC was to kill Miya ASAP an ambush like me and many other thought and suggested but she didn't do that.
I am starting to wonder what happen to that group of survivors...Because MC does not show any signs or experience in killing people...so either that means A.) Risa is responsible (unconscious attack them?), B.) It was truly a group conflict where they all killed each other...ironic if MC's suggestion on what happen was true C.) Random zombie or invader/raider got in and they accidentally killed each other in the conflict, the raider/invader looting their stuff. D.) -insert other reason-
Risa conflicted about meeting Miya due to being half-zombie. Miya feeling guilty and conflicted about killing her mother...and MC feeling hesitant and guilty about trying to kill Miya due to jealousy.
Really hope Miya is not dead and probably might turn into a half-zombie like the comment above suggested....Either that or she just passed out from exhaustion/Stress/hunger (Perhaps her mother was not feeding her enough food, it Z-Day/Dooms Day after all.) ...Going to be weird and awkward if Miya just randomly suddenly dies like that...
The poly-3some route still 'might' possible and have a chance of happening lol...Assuming Miya is not dead.
