Seaweed's manga / #Adorable(14)

It was rlly cute, and I’m very sad it apparently got cancelled. It’s always the good yuri’s that never get completed.. Anyways, idk if I missed anything but I did find issue with the weird older brother who gave me weird vibes, I think even nina pointed it out. Like they are related, why is he licking his sister’s fingers? Siblings don’t actually do this so they?! And am I missing something or is the maid’s mother’s husband a pedo? Wtf is up with these two weirdo characters
