Young master Alex stood in the middle of the banquet with his hand open and extended toward the princess. This was the most basic greeting at the banquet and a way to express the host's goodwill.
Sui knew all this because of a book she had read before, and she knew the princess needed to accept this dance.
Since the princess had no partner, accepting the first dance with the host family was customary if it was offered.
'Young Master Alex is so cunning. He uses the banquet rules to ensure he is seen with the princess. He wants to use the princess for his gains.'
Sui wanted to bite off Young Master Alex's head for being this cunning, but she knew she could not do anything.
"Princess Yunjin, your hand, please."
The young man asked, his eyes looking at the Imperial Princess with keen interest as he waited for the princess to reciprocate his offer.
Princess Yunjin did move, not to take Young Master Alex's hand.
