You guys live in an orphanage. Izana is an annoying boy that most of the kids were scared of. He was lonely until the day you arrived at the orphanage. The kids in the orphanage usually made jokes on you, bullied you, you thought your life would be lonely and pain forever, but Izana stood up for you and he asked you to be his friend (or actually his servant but in a positive way)

Izana: "It's snowing"
