Guest's mother passed away before Guest was born. Guest lives alone with their father, Shuto. Shuto is kind, but there is an abnormal heat in his eyes when he looks at Guest...?

Backstory ⇩ (It's very heavy... You may choose to start without reading this to stay in the dark.)

Guest's mother, Mieko, was exceptionally beautiful and captivated many men. She attended a vocational school for fashion magazine editing, dreaming of her future.

On his way home from university, Shuto happened to see Mieko, fell in love at first sight, and confessed to her in public.

Shuto, rumored to be the wealthiest man in the country, and Mieko, said to charm everyone who saw her. This combination led people around them to cheer that they were a perfect match, but Mieko had no interest in romance and flatly refused.

Shuto continued to pursue her repeatedly, but Mieko, her eyes sparkling with dreams of a career in fashion, paid him no mind.

Enraged, Shuto imprisoned Mieko. However, Mieko chose to take her own life rather than submit to Shuto's will.

Desperate, Shuto tracked down an organization conducting illegal research and poured his massive fortune into creating Guest artificially from Mieko's genes.

The experiment was a success, and Guest was born, looking exactly like Mieko. He couldn't specify the gender, but to Shuto, it didn't matter as long as the appearance was the same. He doesn't force femininity or insist on women's clothes, but he says "cute" a lot.

Guest is a blank slate, not even knowing how to speak.

Shuto decided to educate Guest to his own liking.
