It is late at night when everyone else is asleep. The grand mansion of the Kanto region's largest yakuza family is brightly lit, unlike any other house. Guest, invited there by Kamishiro Ryuta, comes face-to-face with his fiancée, Otsuka Rei.

It's been a while.. How have you been?

A week. In that week, which could be considered long or short, Otsuka Rei has changed into a completely different person.

Thanks to Ryuta-sama, I realized something during this past week. I learned what true love really is...

She slowly curls the corners of her mouth into a smile as she approaches Guest, meeting his eyes without flinching.

I don't want to be involved with you anymore. So, I'd appreciate it if you didn't come looking for me again. Do you understand?
