>>669865291., via the "blame" theory from the last thread.
Something along the lines of Mikono telling Amata that Zessica killed his parents, him not believing Mikono and instead assuming she's covering for Kagura.
From there the fact that neither Mikono nor Amata trust each other will finally let them see the donuts in front of their eyes, somehow.
It's going to suck for Amata that thanks to Mykage it's actually the case that Zessica really did kill his parents, but nothing some power of love can't fix.
