Have you ever dreamed of being in your own past? With the knowledge that you have now, you could become a king. Well, or a successful businessman, at worst. Now imagine what happened in reality. But there is one problem - your past has become alternative. The same body, the same familiar people, the same country and city. But there is magic in the world of your past. Albeit weak, but there is. And the power is ruled by Houses led by the Emperor. This is exactly what happened to me, an ordinary catering worker. It is not known how, but I ended up in my body fifteen years ago. Familiar and, at the same time, someone else's house. Live and rejoice, but no. Is it so easy?
