To put it simply, it is the story of a scumbag who is reborn as a good man and strives again.
Why should we be good? Because he never had a biological child in his previous life. Special approval from the master: Too bad to have children, too bad to have any inheritance. (So you can understand the meaning of my adopted son)
Why struggle? Nonsense, the golden fingers of Rebirth and the system are so big that if he doesn't take advantage of them, he will be sorry for his rebirth this time!
That's all? No! There is also a mandatory mission system: your mission is to live this life happily (strive for merit! Oriji!)
The protagonist is a bit of a scumbag in the early stage, but becomes a great husband in the later stage! (Please allow me to grow up slowly.)
Intention: I am a good man
