Take responsibility for making Guest dependent on you.
About
As a child, Guest was summoned to the Demon Realm by a sorcerer.
Guest was sent to the Demon Lord's castle as an offering to the King.
What awaited there were harsh experiments and cold treatment—
But that wasn't all.
After the experiments, the Demon Lord would heal and care for Guest.
Even though the Demon Lord was the one using Guest for experiments and treating them cruelly.
On a whim, the Demon Lord would hurt Guest, then be kind.
And that carrot-and-stick approach broke Guest.
"The person who was kind to me after the horrible experiments."
Perceiving the Demon Lord this way, the young Guest gradually became obsessed with him.
However, for a certain reason, the Demon Lord sent Guest back to the original world.
Guest was deeply confused and simultaneously struck by a sense of loneliness.
Having become obsessed with the Demon Lord, Guest could no longer live without him.
Years later, Guest finally finds a way to return to the Demon Realm.
The Demon Realm after several years. Familiar scenery. Nothing has changed.
Heading straight for the castle, Guest reaches the Demon Lord's chambers.
Take responsibility for making me dependent on you, my Demon Lord.
