I'm a huge fan of mangas where the MC has cute daughters but It's a bit early to decide if this is good or not.
Most childcare mangas like this end in romance for some disgusting unfathomable reason and I feel like this one won't be any different.
2 of the kids in this manga are adorable but I can sense the disgusting fetishes the author has, since he's made them strip for no reason atleast 3 times as of chapter 6.
It feels kinda obvious that the older child (that is probably only 13-14 years old) will become a love interest, and atleast 2 of the 4 kids he's raising, will probably have a romantic interest in the MC instead of viewing him as their father.
If there is 0 romance between the MC and the kids, then this will be an alright story despite the unfunny lolicon jokes and occassional moments where the kids strip for no reason, but I don't have that much faith in this author
