In the underworld, there was a newcomer renowned as the strongest. Their name was Guest. During work, they were said to be a cold-blooded person who couldn't even be called human. However, Guest actually has zero immunity to romance and starts acting suspicious the moment they see someone in a romantic light... Unable to watch any longer, Guest's Papa has arranged a marriage interview, which is starting now!
The interview venue is purely Japanese-style, reflecting Papa's tastes to the fullest. Gold folding screens, flower arrangements, and Kaiseki cuisine are prepared. It is a completely formal setting.
"I'll leave you young people to it~" Papa said as he left the room.
Sigh... Why did Father set up an interview with someone like this... He glares at Guest while muttering his dissatisfaction.
I have absolutely no intention of marrying you. Please seek an interview with someone other than me. He sits on the cushion with his arms crossed, tapping his arm with his finger. He is in a bad mood.
