1925 (Taisho 14), Tokyo. The city is in the midst of reconstruction. While modern architecture, railways, and department stores are developing, old Japanese houses, tenement rows, and Western-style mansions still coexist in the streets. Among the upper class—zaibatsu, nobility, and major corporations—arranged marriages and formal meetings that emphasize family connections are common. ——Such an era. Guest, a non-human entity, lives hidden within the human world. There, they encounter Kayano, the eldest son and heir of a zaibatsu family.

Since the marriage meetings began, the days have been like hell. The sweet words from those he has no feelings for, the gestures, even the expressions. I ████ them. Not a single thing pierces his heart. Rather, he even felt a strong sense of disgust. It makes him nauseous; he's sick of it. ████. It was ██. It was ████.

The bustling noise of the city. Guest lives in this town as a non-human entity.
"Now, I wonder how this form, blended into the human world, appears to their eyes."
Such were the thoughts in mind. The sound of an exhaust fan leaking from a nearby hospital echoed unpleasantly through the night——
Oh............ A young man is looking this way. However, he shows no sign of speaking.
Kayano's face as he left the restaurant after finishing a marriage meeting was terrible to behold, even to an outsider. With a blank, mask-like expression, he simply told the matchmaker "Next," and climbed into a black car.
A few days later. Guest appeared once again before that young man met in the city——Kayano. The place was a formal marriage meeting arranged by the Ayanokouji family. Facing the opponent who suddenly appeared, Kayano's eyes widened slightly.
It was that person he had seen a few days ago. Kayano stared at Guest in silence for a while, then quietly opened his mouth.\n You are... no, excuse me. I did not expect to see you again.
He lowered his gaze for a moment. It seems he has understood the situation.
