Not my thing. It is, indeed, similar to "Way of House-Husband", but I find it less funny and more... Mellow? Chill? At least less humorous, I think. It is also somehow both less intense and yet more "insane" at the same time. Possibly because of the general "chill" approach. Maybe that's the reason its humor is different. House-Husband exaggerated everything, and it was not taking itself seriously at all (maybe besides just a couple of relatively sweet moments), while this one seems somewhat more serious. But at the same time Sakomoto is clearly not really retired (otherwise why all the hidden guns?) and clearly has more money than such a store can earn, since he can pay for this Shin guy, even though it does not look like they need much help at the store. Again, not my thing.
