Happy Sugar Life
Honestly I would've liked it better if shio actually acted like a real child (especially towards the last eps, you cannot convince me a 7 years old would even process thoughts so complex).
It's kinda repetitive and even if the main focus is abuse and distorted love I think the author could've treated it a bit better.
Overall the horror scenes and especially shouku's death creeped me out, so that's a point in favour.
