From what I remember in the novel, the Prince came to the party after Rain told him that he might've mistaken the wrong sister and the Prince decided to confirm it for himself. The Prince just gloriously walks in to the party, looks at Mielle and say "Nah, she ain't you", then just leaves, leaving everyone shook. I think it kinda shows off his dominance in the novels
But this chapter was hilarious and I very much prefer this over the novel
