@BoobTwinkler: you sound like a picky eater. Gyoza without meat is normal, so is tofu mackerel sandwiches and the cream croquette looks delicious. Dry curry with oatmeal is indeed a bit strange, but potato salad with oatmeal? I'd definitely try that.
Ruka seems to be at least a lil into Ritsu from what i see, Like a super reliable wife that takes care of her wife, maybe she really does wanna bang ritsu but I guess I'll wait for more chapters to really confirm
