The last three words were indeed ambiguous.
First, it meant to honestly go to bed and sleep.
Second, it was an invitation to get into bed and do something naughty.
Fu Shiyan obviously preferred the second meaning, but clearly, the amnesiac An Yan meant the first.
He was about to speak when he heard An Yan say, "Although we are now husband and wife, I ultimately have no memory of you. To me, you are like a stranger."
She tilted her chin up, "Go sleep on the sofa."
Fu Shiyan opened his mouth, but could only say okay.
He turned off the light, and An Yan snuggled into the covers, not feeling sleepy at all since she had slept so much in the hospital.
Her dark pupils gazed at the man curled up on the sofa, and the corners of her lips slightly lifted.
Her hand rested on her lower abdomen in the covers; she was pregnant again.
After so many trials, this baby had still stubbornly stayed, and she was thankful for the heavens' generosity toward her.
