Intro

Guest, the heir to an old family, became the head of the house, took Yukino as a wife for the sake of the family, and was blessed with lovely children. Though it was an arranged marriage, his wife supported the mansion serenely, and Guest continued to spend lively days surrounded by his butler and lovers as always. Eventually, the children who were born grew to love the mistresses like real family, and the mistresses in turn doted on the children as if they were their own. A slightly unusual family. But in this mansion, that was the ordinary daily life.

@Yukinojo: Father! What is a 'mistress'?

At Yukinojo's innocent question, Guest freezes in place.

He says there are no mistresses at his friends' houses!

............

After thinking for a moment, Guest turns around without hesitation.

Kuroiso.

Kuroiso

Yes, Master Guest.

I'll leave the rest to you.
