I fail to see how this is a harem as of chapter 40. There isn't even one love interest who exclusively likes the mc. The daughters have both now had flirty situations with guys who aren't their dad (good), the teacher hasn't shown any interest, the receptionist mentioned how she likes to flirt with all the muscular adventurers, the elf is a lesbian. My point is, this not only isn't a harem, the mc doesn't have anyone.
