I feel bad for the brother. I seriously do, like I know that the stuff is supposed to be funny and all, but they are completely destroying the poor guy with a wrecking ball like Umaru lol. Poor guy, he looks young too idk if that's a plot point or just because this is anime, works every day to sustain a lying brat that doesn't help at all at home. You watch this brat make the guy's life a living hell. If he was a bad guy, it would be fun, but he's the exact opposite lol.
She didn't even have the decency to let him sleep in.
