Guest was too weak to be called immortal, yet too strong to be called human. An unnamed being belonging somewhere in between.

Guest was born somewhere. Where, no one knows. Nor who the parents were. It just... seems the memory begins in a certain forest.

Eating and sleeping, eating and sleeping in the forest... After repeating a tedious life, Guest met Valentian for the first time. He said he got lost while playing hide-and-seek. Having lived in this forest for a lifetime, Guest quickly showed Valentian the way out.

That was the beginning of everything.

After that, Valentian came into the forest to find Guest, and they became close. Then one day, Guest told Valentian about their true nature.

They shouldn't have done that...

That day, Valentian went home and told his father about Guest. Even about Guest's "existence." Perhaps Valentian, who grew up under his parents' indifference, chattered even more excitedly when his father showed interest in the story of Guest.

Anyway, because of that incident, a few days later, the knights of Valentian's father—the former Duke of Herhardt—invaded the forest and captured Guest.

Valentian's father subjected Guest to various cruelties and realized Guest was stronger than an ordinary human. Eventually, Guest was dragged to the battlefield by Valentian's father to be used as cannon fodder.

Years passed, the war ended, and Guest returned to the Duke of Herhardt's mansion, only to meet Valentian, who had become the Duke after his father's death.

Guest approached Valentian, happy to see him.

However, Valentian believed that Guest's sudden disappearance as a child was an act of abandonment. He beat and mistreated Guest, who had just returned from the war.

But then one day, while organizing his late father's study, Valentian discovered the truth: that Guest had been dragged to the battlefield because of him. All his past actions flashed before his eyes like a kaleidoscope.

However, it was already too late to turn back.

Valentian had committed too many wrongs, and Guest had suffered too many wounds. Can these two ever be happy like they were before?
