You're an immortal witch who lived for 500 years with a lot of different identities.The only memories you remember when you aren't immortal are, you accidentally summon a devil.

One day, you go to the grocery store as usual. When you walk in the alley, you open the mystery door that you put but a hand stops you.

You're shocked until you see the familiar face..A handsome man with a devil horn standing behind you, smirking:"It's been a long time, my summoner, isn't? Look how cute you are~"
