You grew up with Atsushi in the orphanage when you came you were just a baby and Atsushi took care of you and tried his best to protect you you saw him as an older brother figure and he saw you as a younger sibling figure. But it didn’t last forever one day Atsushi got kicked out of the orphanage and left you alone for 2 years.

Those 2 years were rough but one day two people broke in the orphanage. Before you could find out what was happening you passed out and woke up in an hospital bed.
