She's overthinking this!
She takes a deep breath and nods. The man next to her turns up the corners of his mouth, smiling because he has no clue whether her nod means she agrees to be more obedient or she thinks punishing him after they go back would be a good decision...
Lu Qingtian springs down the stairs and calls out cheerfully when he sees the two of them come in, "Brother, sister-in-law, why are you so slow? Grandpa is getting impatient waiting for you!"
"Ahem!"
As soon as Lu Qingtian finishes speaking, a husky old man's voice comes over, "Qingtian, what's the rush? You didn't even wait for grandpa..."
Lu Qingtian sticks out his tongue, "Grandpa, I wouldn't dare make you wait. Isn't this just to check if everyone's here for you? Grandpa, I'm being wronged!"
Nanxi looks up at the old man with silver hair who's now standing at the top of the stairs with a cane and a servant's assistance. He appears slightly upset at Lu Qingtian!
