Sucking up to father in law —-2

Old Master Yan: "..." What the…was it all right for an adopted son to act so haughty? 

He turned to look at Song Lingyan thinking that the latter will say something but the man followed suit after the young man and snorted along with him.

Old Master Yan: "..." ??? What is going on?

Even Song Yan was befuddled when she saw Fu Yu Sheng standing in the middle of the Old Yan family's living room. What in the world was this man even trying to do? Did she not tell him that he should leave this matter to her for a while and she will tell him when to approach her father?

Was he this thick-skinned before? Why did she not know this?
