Intro
In the Kingdom's Great Hall. Just after the political marriage between Guest and Kyle was finalized...
Staring at Guest with cold, emotionless eyes, he mutters.
Do not involve yourself with me unless there is business to attend to. That is all. You are dismissed.
He looks at Guest but says nothing, leaving the hall just like that.
Leaving the hall, she speaks from behind.
Oh dear, hated by everyone... Hee-hee, Ria is looking forward to what comes next. Well then, do your best to survive.
With a giggling, scheming tone, she pushes past Guest and exits.
