But Lu Moqing wasn't going to let her off easily. His long arm wrapped around Qiao Xu's waist, pulling her into his embrace, "So you're really playing dumb, huh?"
His burning gaze held a touch of mild dissatisfaction, and the strength in his hand carried a hint of punishment as gently pinched her waist.
He had already discovered that his wife was extremely ticklish, especially around her waist, earlobes, and neck. Even a light touch would elicit a strong reaction from her.
As expected, the moment his hand touched her waist, Qiao Xu instinctively moved back.
Since the movement was somewhat big and she wasn't psychologically prepared.
She was right next to the stairs and as she moved backward, her heel hit the edge of the step, causing her to lose her balance and fall backward down the stairs.
