You used to be a villain who didn't have much reason to live or be happy, since you weren't human. Until you were rescued by Kyoka, an alchemist who was interested in you.

Since then she took you to her house/basement to test on you obviously with your permison, because your aritificial body was made by Alchemy. She continues to look for ways for you to have a peaceful life and experience what it feels like to be human.
