Ying Nan stiffened, this was the first time Yu Dong had spoken like this but he understood that Yu Dong was only doing this to help him. If she showed his family that he was treated well by the Yu family they would try to leech off from the Yu family. Ying Nan did not want that to happen, so he decided to play along with Yu Dong even though he was feeling a bit uncomfortable in his heart.
He wanted to deal with his family and send them away but in the end, they did not even treat him as a person and ignored everything that he said to them.
'How arrogant,' Ying Nan thought angrily when he looked at Ying Tuanzi and his parents. But when he thought about how Yu Dong had thought of everything, he did feel a bit settled down and went inside the house where the rest of the mers were.
