But those are also usually scenario of first or second time around. Bro's on number three, he wants someone else to do it this time.
Was this meant to quote someone else? Because I'm not really taking issue with the nature of the MC as the guy that wants his slow life because he's been the hero before.
My entire train of thought is about how if this series is meant to be a parody of these sorts of stories as another poster suggested, it's not doing a very good job because there is nothing to distinguish it from a normal, played-straight version of the concept. There are lots of stories of someone reincarnating into a world where they have fantastic power and can be a hero or change the world but they just want to laze about and not care. So him having been the hero before and not wanting to repeat it isn't any different. Ditto for getting sucked into helping others by accident. Or the wacky silly nonsense characters, or the preposterously thick antagonist family/aristocrats/whatever. Even the fact that this series just out-of-nowhere goes for slapstick and goofiness is not abnormal because lots of "serious" manga and anime are broken up by completely random bursts of zany comedy because that's just how Japan does things.
The issue is that as a straight example of this sort of genre it's nothing we haven't seen dozens of times before. And as a parody/gag version of the genre it's handicapped by the fact that the genre almost always makes fun of itself even in straight examples, taking away the teeth of the parody angle. It has nothing that makes it stand out at all.
