I remember reading something similar to this but without isekai troupe. It was like famous chef but he went to some like rural area and opened his restaurant there and even the initial scene of them eating like in a warehouse was literally same as in it.
There was a movie in which the child goes home with his wife (btw they run away to marry in past), and they also stay at his parents home at night. But.... During midnight, the villagers along with their parents burn him and his wife. ik it won't happen in this manga
