Even for the 'step-bro who raised the other after both their parents died' genre (WHY ARE THERE SO MANY? AND ARE ALL 4 OF THEIR PARENTS DEAD!? WTF SURELY THERE IS ANOTHER ADULT TO RAISE THEM-- *ahem*) this one ranks real high on the 'holy crap that's just grooming' scale. Normally they try to offset it by having the younger one be physically bigger, or yandere, or at least the seme, but nope, we just got a like decade-older brocon who raised his little step-bro from the time he was a child and doted on him excessively and took all of like 1 day after hearing his younger bro's love confession to go from seeing him as a child to seeing him as a romantic interest. Oh, and even works as a teacher at his brother's high school, as if the mangaka didn't feel the rest was enough!?
Was making my way through Ichikawa's series but I should've skipped this one, and idk why I even bothered finishing it. Ew.
