It's actually quite good - they have decent adventures, each character feels like actual beeing and girls from former hero's party have they own backstories, the mc is not hardcore virgin but understands, that he needs to tend to his sexual urges; dialogues feels thought-through, the art is unique enough and works good with occasional slapstick comedy.
Sure, there cliches and everyone praise mc to the heavens, but that kind of thing is kinda comes with the territory.
Also technically there is harem, but it's not like every single female wants to get married with mc. From the start there is strong suggestion just to one girl and others are kinda part of comedy or they appear so rarely, that it doesn't even matter.
Funny thing is that females from former hero's party consider mc as dear friend, but not as love interest.
It's really too bad, that no tl picked it up, since it's one of the better stories with the trope "kicked-out from the party" and cool fantasy/comedy/adventure manga on it's own.
