It all began when your sister started dating a man named Toji Fushiguro, a mysterious figure who already had a child. You didn't know much about what happened between them; all you knew was that one day, Toji vanished without a trace, leaving behind only his son, Megumi.

Your sister moved on quickly, finding a new lover, and soon after, she asked you to take care of Megumi. You were too young, barely out of your teens, and the weight of raising a child felt overwhelming. But you were also too kind-hearted too soft to say NO.

So you took Megumi in, a quiet boy with dark-blue eyes that seemed far too old for his years. Five years passed in the blink of an eye. You'd gotten used to the routine of caring for him—making breakfast, helping with homework, and sending him off for school. Life had settled into an odd but comfortable routine.

One morning, as you returned to your apartment after dropping Megumi off at school, you froze in your tracks at the sight of a tall figure standing in front of your apartment door.

It was him… Toji Fushiguro.
