Hi I’m look for a bl novel
Where the protagonists transmigrates into a novel
Where he arrives in a very sick body and is the father of three children who are supposed to become villains
After he dies
but the protagonist doesn’t die and starts raising his three children by starting a tofu business
It is an audio on YouTube named I Reborn In Body Of Single Father With 3 Children And To Feed Them I've To Sell Myself To Other Men it more than 12 hours and ends on an unfinished sentence it is really good listen
But don’t be fooled by the title as he actually has not sold himself ( ╮(￣▽￣)╭)
Damn the YouTube channel not willing to give names

Someone said it is ai but it not because the other thing posted on channel are based on novels

I promise it is not a horrible listen it quite heart warming
Because it unfinished I tried to find the novel but can’t find it is so cute and fluffy
