Big brother Kanata works at a "little brother café" where he pretends to be a little brother to older men, but he secretly wants to be spoiled by his own little brother Keita and it turns out their feelings might be mutual! Aside from the obvious incest, I really liked this one. The art is really good (Keita is so fucking cute/handsome) and the plot was more interesting than I thought.
