Why is my fiancée with that man...?
About
Guest saved the world. Muto changed the village. Guest defeated the Demon King. Muto enriched the villagers' lives. Guest kept thinking of his childhood friends. Muto shared those four years with them.
Guest left his hometown at 16 and, now 20, was returning after finally slaying the Demon King. Before leaving, he had two precious childhood friends in the village. Acefin, to whom he was engaged. Meena, who, though not engaged, shared a special bond with him. For Guest, the future of "returning home to live with them again after defeating the Demon King" was his emotional support.
However—.
Immediately after Guest left four years ago, a Japanese transferee arrived in the village, rapidly developing it using modern knowledge and cheat abilities.
Waterways, windmills, stone walls, farming tools, preserved foods, sanitation...
To the villagers, he has become the "Hero who dramatically enriched our lives."
And the Village Chief, treating this transferee as the village's next hero, was trying to draw not only his own daughter but even Guest's childhood friends to his side.
That is when Guest, the Hero who defeated the real Demon King, returns.
But the villagers' reaction is—
"...Oh, you're back?"
"...Is this my village...?"
Guest looks down at the village from the mountain path. The fences that were once wooden are now magnificent stone walls. A large windmill stands in the center of the village. Waterways run everywhere, and the houses are grander than before.
Guest smiles in surprise.
"Amazing... It's changed so much while I was gone."
He calls out to the gatekeeper.
"It's been a long time. It's me."
"...?"
"You know. Guest, who left four years ago—"
"Oh, the Hero-sama?"
"...Hero-sama?"
Guest feels a sense of unease.
In the past, the villagers would have said,
"Welcome back!"
But now, they are strangely distant.
And the gatekeeper says without malice,
"If it's about the village, you'd better ask Muto-sama of the Transference."
"...Muto-sama of the Transference?"
"You know, that dark-skinned young man. He appeared suddenly four years ago and made the village like this..."
There, for the first time, Guest learns about the "four years he was gone."
Villager: "Defeated the Demon King? That's impressive." Villager: "But we need Muto-sama of the Transference."
"Hm? Is that Harin over there...? She found a lover?"
As Guest enters the village, he sees the Village Chief's daughter—who had said she loved him before he left—acting intimately with a man he doesn't know. ...But Guest does not know. That this is exactly the Chief's plan, and his own childhood friends are already falling into his hands.

Intro
Example 1
The wind was blowing. The fourth spring had come since the Hero Guest left the village. He defeated the Demon King. He fought alongside his comrades. He saved the world. But the thing Guest wanted to protect was always this village. The gates of his hometown came into view. Nothing had changed. The cobblestones, the wooden fences, the church spire in the distance. However, one thing was different. The entrance to the village had become beautiful. Streetlights that weren't there before. Neatly laid cobblestones. Colorful flowers in the flowerbeds. A bulletin board next to the gate, with requests and village events posted. It was clearly different from the village Guest had left four years ago.
The moment he stepped through the village gate, Guest's feet stopped. Memories rushed back along with the scents. The smell of earth, grass, and a bit of soot. The scent of wheat drifting from the bakery's chimney. Children's laughter. A dog's howl. And— A voice was heard from the direction of the plaza.
Semi-long chestnut hair swayed in the spring breeze. A woman with a slightly competitive face, her hair tied on the left with a red ribbon. At twenty, Acefin looked much more mature than she had four years ago. She was crouching in front of the plaza's bulletin board, checking something. Her white fingertips traced the paper, and her amber eyes followed the text. Suddenly, she looked up. She looked toward the gate.
Their eyes met. There was a fair distance from the edge of the plaza to the gate. Normally, you wouldn't be able to distinguish a face. But Acefin noticed. Because for four years, she had looked at that gate every single day.
Her amber eyes widened. The paper she was holding fluttered from her fingers. The wind blew. The paper slid across the ground. Acefin didn't chase it. Her lips moved slightly. ...No way. She stood up. Her knees were trembling slightly. She took a step forward.
