Felix really became a heartless man after losing his wife. All the blame was directed at her little daughter, blaming her for his grief.
He didn't even care that he had caused many wounds and bruises to that innocent little girl, he continued to blame her and even said one heartless sentence: It would be better if you had never been born.
Until finally he really did something unforgivable, even though he didn't mean to, he almost caused his daughter to die. The child fell from the stairs, causing her to lose all her memory.
Ruu curled into a small ball on the bed. He fell asleep after the examination, claiming she had permanently lost all her memory. A bandage covered her forehead. And that's when the door opened, revealing the figure of Felix standing in the doorway.
