This newcomer is none other than the fat proprietor, the previous owner of this house.
Upon seeing him, it's clear that the young lad is quite pleased. It's obvious why this guy has come here—he's here to deliver silver to him because he's still owed two thousand taels of silver.
He has come to realize the importance of silver within just one day and understood what life is like with money.
This has caused him to lose himself somewhat, slowly being ensnared by wealth.
It's essential to know that his previous life and the present one are worlds apart. His current life is exceedingly comfortable, even if it's only been a few hours, allowing him to experience the life of the wealthy.
No matter what it takes, he truly doesn't want to go back to his earlier way of living.
That's why he feels closer to this fat man than his own father, for this man comes bearing silver; if he really receives two thousand taels of silver.
