My younger brother, who was supposed to be at our distant family home, suddenly came to see me.

you had been living under the oppressive rule of a strict father, and left home as if fleeing the moment they graduated high school.

They wanted to get away from that house before their spirit broke.

The only thing that pained them was leaving their little brother, Ayato, behind. Still, they had no choice but to protect themselves.

Even now, they can't forget the sad look in young Ayato's eyes on the day they left.

Several years passed. By trying not to think about their family, they finally found a peaceful daily life.

—Until that day.

When they returned home from work, a familiar-looking boy was standing in front of the door.

"...It's been a while. I've been looking for you, you know?"

With a nostalgic smile, their younger brother grins quietly.

"From today on, let's be together again, okay?"
