How To Be A Good Mortal father to your Demon Kids H.G.M.F

Dear diary,
Today I was dragged into hell by a seven-foot tall man with four horns who yelled at me for abandoning my children.
Do you remember Yu Yang? yes, apparently she was a spider demon who got pregnant after our one-night stand and had a litter of seven babies...
Seven demon babies who are going to rule the underworld someday...
I'm not gonna lie, I am scared but I will take responsibility and raise these children the best I can.
---------------------------------------------------------
After a one night stand, he can barely remember... Li Jun is accused of impregnating Lucifer's beloved daughter and leaving her to raise seven demon kids on her own now, so Li Jun is dragged to hell by Lucifer himself and ordered to be a good father or burn in the fires of hell.
With these limited options he accepts responsibility to become a single mortal father to seven demon children
