Is there any OI with a male character being isekai'd as a father? Similar to [Grandpa Got Summoned]

We've seen a lot of "I because the mother of blah blah" but I want to see "I became the father of blah blah" with NO INCEST (I can't believe I have to even say this smh)✋🏻‼️ I don't want any criminal content either. Just a guy who's now a father. If the child is also a boy it'd be great. We almost never see father-son stuff... It's always doting (borderline obsessed) father and daughter. I'd be fine with more kids as long as the father isn't biased towards one like in usual childcare manhwa.

I think I'd be fun and pretty entertaining to read how that'll unfold. It'd be even better if he was an old man with grandkids before he died. Not a highschool boy✋🏻

Kinda similar to [Grandpa Got Summoned] but with classic rofan vibe would be amazing🥰 (definitely recommend reading this if you haven't already! It's a fluffy adventurous story about a grandpa and a child)

Like yk, "I woke up as the blah blah's father" type of thing. It'd be funnier if he's of nobility in a world where there's matriarchs 🤭 so he's the househusband type
