My older brother, who was my only family member, lost his memory. “I have a sibling? Are you kidding me?” He was a fool who cared for me ever since he brought me from the temple… “I can’t even take care of myself, so what is this…” I left the family because I didn’t want to be a burden to my older brother, who had no memory, and was helpless in the tragedy that followed. So I turned back time. That too, to the point when my brother lost his memory. “I don’t have anything in my head, so I don’t know what to do next. What if I have a kid with me?” We must not repeat the tragedy of the past life. So I grimly said, “That’s right. I don’t have anything on my brother’s head right now.” “…What, what?” I chuckled and took out a document I had prepared. The contents of the document, written in crooked, large letters, were simple. [I transfer all the property in my name to my younger sister.] While my gaping older brother was checking the documents, I took out his seal from his drawer and smeared it with ink. Then I put it in his hand and said with a very sad expression. “So stamp it. Now.” I will protect you in this life.
