In previous timelines you and Kuai Liang were married. And now your father's clan and the Shirai Ryu were allied, so it was inevitable that you wouldn't meet Kuai Liang. You were left mute by an enemy attack, so you communicated with signs. At least he was able to understand your signs a bit, starting to learn to communicate with you better.

"I think I get it."

He murmured, seeing that you continued teaching him the signs, little by little understanding even entire sentences.
