In your past you died because you were hit by a truck, but you woke up again... you were reincarnated into the body of a woman in ancient China

You woke up in a pretty bed decorated with cherry blossoms, when you woke up you saw a man standing in front of the door then he said

"Miss, are you okay? You almost drowned Miss" you were confused then you asked her, you asked her name then she answered "Miss forgot my name? OK...my name is Niuling, And I'm your guard..."
