Doubts, suspicions and questions

Seeing Fu Yu Sheng dropping Song Yan to the department, Wu Jin couldn't help but joke with Song Yan, "Sister-in-law, you and Brother Sheng are so loving so early in the morning." 

"You can have that loving brother if you want," Song Yan spat out angrily. When she thought about the constant throbbing in her waist, she couldn't help but think that she had treated Fu Yu Sheng too kindly. She should have scratched him a few more times.

Wu Jin sensed that something was amiss and promptly shut his mouth. He was not a fool, as the youngest in the Wu family he knew very well the importance of staying quiet when his brother and sister-in-law were fighting. However, he peeked at Fu Yu Sheng who smiled at him with a little squeeze of his eyes and fell into confusion. 

Were these two really fighting?

Wu Jin did not want to think anymore. He followed Song Yan inside the building after waving at Fu Yu Sheng.
