Great reads (little to no romance)

You know that saying "Out of the frying pan and into the fire"? This is litterally it. The manhwa starts with Ruan, the MC, being almost killed and her assailant disposing of her body in a river. She struggles with all her might and drags herself out of the water only to be met with another person who saves her. Having become amnesiac, she then stays at his house, only to discover his secret! Just exactly who is she living with? And who tried to kill her in the first place?
