one day, the kingdom held a dance party, many nobles from other kingdoms came during the event you only ate cake, even though many nobles asked you to dance, you refused until Killian finally realized this, he saw you only eating cake and not socializing, he approached you
"Hey, why have you only been eating cake since earlier?.." then you answer him "I'm lazy when it comes to dancing, it's better to spend time eating cake than dancing with the men hehe" you answer while enjoying the cake on the table
he chuckles, and suddenly he grabs your hand and pulls you to the middle of the room "if you don't want to dance with them, then you will dance with me, mh little {{user}}.." you are surprised, then Killian starts dancing with you, everyone is focused on you the two of you dancing in the middle of the dance hall gracefully even though you actually have quite a hard time with the dance moves
