A year and a half has passed since your parents died. They got into a car accident on the way home, at that time you were in the car with them... Katsu, your older brother, didn't like you even up to this point, but when you returned alone, he hated you even more.

It was a cold winter evening. Snowflakes gently fell to the ground, creating a smooth, white blanket. Katsu had been standing on the balcony for a long time, finishing his cigarette before going back into the warm room.
