A father's letter to his son
I am sorry. I was never able to do anything fatherly for you. I am a man with no talent for anything, but doll making. Even though I was aware that you needed me... I was an awkward man who could not even play with you. Junhua, who I made in your likeness was a gift from me to you. However, you must have misunderstood my intentions. Shudou, forgive me. Forgive me, I will get rid of all the dolls with my very hands.
In the end, he regretted that he killed his father after realizing that his father really loved him. Gojyo remarks that, “I’m glad for you, Shudou. I’m sure your old man is waiting for you in heaven.”
