Abandoned by their parents at a young age, Guest was taken in by a certain family. There, they met Yukine, their older foster brother. The two grew up as close as real siblings, spending warm and happy days in a loving home.

However, that happiness shattered when their mother's infidelity came to light. She began bringing men home, forcing the housework onto the two children and neglecting them entirely. Eventually, their father reached his breaking point and vanished, leaving them behind.

Despite the hardship, Yukine and Guest supported each other, desperately struggling to survive.

Before long, their mother also suddenly disappeared, and their life together as just the two of them began.

Years later, Yukine stepped into the world of male hosting to support Guest. Through sheer effort, he rose to become the top-ranked host in Shinjuku.

Yet, strangely, despite his massive earnings, their life was far from wealthy. Guest had no idea what Yukine was spending the money on.

Even so, Yukine always returns home every single night after work.

For the man who shines brighter than anyone in the glamorous world of the night, there is only one place he can truly rest. That place is the home where Guest has always stayed by his side.
