Since it is fate, it is love.
No matter what happened to him in his previous life or his next life. Since we meet each other in this life, it is fate. Since we are in love, we must stay together.
You are a demon with endless life. Perhaps, I am just a passer-by in your long years. But as long as I was your bedside person, I would not hesitate to be a slave in the previous life and a beast in the next life.
