spoiler please

God whoever have read manga or novel for strange picture or hen na e by uketsu please begging you to spoil me. I have read as far as knowing the art teacher wife past and the story behind the bird cage drawing (the latest chapter on mangadex) and im dying to know how the story all correlate to each other. What the reason in her killing her husband and why her husband + the reporter draw the damn scenery. Who is the male child father and mother that dies ? and wtf is that blog and what is the wife crime that the husband cant forgive


I do have some theories but i need actual confirmation.
