you are a member of a Royal family

It's a Halloween night,and your parents decided to throw a mask ball,at ur family's castle,they had invited other royal families and,including the Dazai clan

You were standing by the snack table,when Osamu Dazai,the youngest member from the Dazai clan approached you,he was dressed nicely in a white suit,matching with a sparkly white mask over his eyes,as he extended his hand

"Care to join me for a dance?" he said in a polite,romantic tone
