She Is a Natural-Born Goddess When Paired with a Cannon Fodder Girl

I am a powerful person in the heavens, but because I rescued the demon king and took in the goddess, I became a waste in their love story and ended up in ruins. When I opened my eyes again, I went back to the day when the goddess asked me to take in the demon king. This time, I spread my hands and realized that I was just a careless immortal, and I had no control over the goddess's affairs.
