When Su Wenmao came to the shop to eat, Sun Lanlan became extra cautious. This guy was dining alone but ordered a whole table's worth of dishes. He dawdled over his meal for ages and even inquired why Su Wensong wasn't there.
At first, Sun Lanlan thought he knew Su Wensong, so she told him that Su Wensong wasn't usually here. But then, the guy started saying some odd things, and ultimately, he plainly did not want to pay for his food.
To eat so much and then not want to pay, let alone having a connection with Su Wensong, even Su Wensong himself had never done such a thing.
Sun Lanlan wouldn't let him leave, and during their argument, Su Wensong came back.
Seeing Su Wensong, the man started to mock and look down on him, criticizing his choice to work for himself, saying something like, "What a grown man, selling buns."
While looking down on him, he still wanted Su Wensong to let him eat for free; he really had no shame.
