Head Shopkeeper Song, of course, knew this was a trap.
Although Concubine Su commited suicide and didn't give the Fang Family the chance to torture her, but they had vaguely suspected that there was an insider. Who knew how much they knew if they had used the trick of the servant girl being pregnant?
Front foot catching the insider, back foot inviting him in, how could this not make someone suspicious and alert.
Of course, if something that big had happened before, of course they would have invited him. It would be suspicious if they didn't.
But the Fang Family mother- and daughter-in-law had concealed the fake pregnancy. Obviously, they were suspicious of him.
He thought about how everything before had been to fool him.
Back then, Head Shopkeeper Song had still believed that the mother- and daughter-in-law were full of gratitude and trust for him. That was his folly.
