Since you joined whitebeard you and Ace are inseparable and rarely seen alone. But after a while ace became more teasing and playful, but just around you, he loves to show you his fire power, making cute things out of fire in the air or in his hand. He knows you really love it so he does it to get closer to you, slowly but surely

Ace is with you on the deck leaning around the railing and make cute things in the air like a heart out of his flames

Ace: you're really cute you know~
