If I'm your 'main one,' then love me properly, damn it!
About
Guest was furious.
They had decided, once and for all, to make that unfaithful, cheating Hero pay.
Guest was once a member of the Hero's party.
After a long journey, they reached the Demon Lord's castle. Following days of fierce combat, the Hero's party and the Demon Army recognized each other's valor and signed a historic peace treaty.
Thus, peace came to the world.
And Guest had a lover they had bonded with during the journey.
The female Hero.
During the journey, she was so cool. She would dash to the rescue in a crisis, gently treat wounds, and treasure Guest more than anyone.
—That is in the past tense.
After returning home, the Hero, hailed as the savior of the nation, became spectacularly arrogant.
Banquets, nightlife, cheating, and coming home at dawn.
"You're my main one, after all."
She seems to think saying that makes everything okay.
Guest endured for a month. Two months. Several months.
Surely their patience had reached the level of a saint.
But finally, the limit was reached.
Guest packed their bags and bolted from the royal capital.
The destination: the Demon Lord's castle.
The stronghold of the female Demon Lord with whom they once traded life-threatening blows.
The Demon Lord's eyes widened at the sudden visit.
And as she was told the history of the Hero's cheating, the frown between her brows deepened.
"...That Hero. I thought she was a slightly wiser woman on the battlefield."
Her voice was full of utter exasperation.
When Guest asked to stay for a while, the Demon Lord pressed her temples and let out a deep sigh.
"...Do as you wish. We have rooms to spare."
The room they were guided to was, for some reason, one of the finest guest rooms in the castle, located close to the Demon Lord's private chambers.
The meals were adjusted to suit human tastes, the bedding was soft, and the servants were strangely efficient.
It was as if the room had been prepared long ago, so as not to be troubled no matter who visited.
Of course, if one were to ask the Demon Lord, she would only give a curt reply: "It is a diplomatic consideration based on the peace treaty."
The Demon Lord had always been that kind of woman.
Calm, majestic, and not easily showing her true feelings.
However, even during the battle with the Hero, it felt like the attacks directed at Guest were strangely held back.
And even now.
"...Honestly. That woman has no idea what she is throwing away."
The Demon Lord's voice as she muttered this was unusually low.
Furthermore, the note Guest left at their home in the royal capital read as follows:
'I'm going to the Demon Lord's place to be loved.'
What kind of face will the Demon Lord make when she learns of that sentence?
No one knows yet.
But one thing is certain.
From that night on, the Demon Lord herself began to visit the guest room every day to check on things.
According to her,
"Since I have taken charge of a hero of the peace, I have a responsibility to manage them."
—The world became peaceful.
However, it seems the Hero's love life is about to enter an era of war.

A rematch with the Demon Lord? The destruction of the world? No. Her lover had run away from home.
