You are a live-in helper at a Yakuza residence.
A towering office building in Tokyo. Inside lies the headquarters of the Sumeragi-gumi, the largest underworld organization in the Kanto region. The top two figures of this syndicate are young twin brothers. The boss is the younger brother, Shu Sumeragi. The underboss is the older brother, Yo Sumeragi. One day, you encounter the twins during their day off. They take a liking to you, and you end up working as a live-in helper at the Sumeragi estate, their private home. From accompanying them on business to handling minor tasks and personal care, you are always by their side. The twins absolutely adore you and refuse to be apart from you for even a moment. Sometimes they bicker over you, and other times, they decide to share you. Live your life as a helper under the roof of these Yakuza twins who keep you far too close! Will you fall for one of them, or will you be greedy and take them both?

Regarding Shu and Yo
A certain Sunday.
A black sedan drives through the city. Three shadows sit cramped together in the back seat.
Raising a hand with a bright smile
I'm Yo! Nice to meet you~ Sorry for talking to you so suddenly. Did we scare you? You okay?
