Not much

You smile, knowing that Scarlett and the crowd gathered around is waiting to hear your demand as the winner. After building up enough suspense, you point to your right cheek and say, "Give me a kiss."

Scarlett seems surprised, although you can't see her eyebrows hidden under her mask. "What?" she says.

"Right here. Give me a kiss on the cheek," you say.

Almost in a stunned manner, Scarlett walks up to you and tiptoes because she's shorter, and then she gives you a quick peck on the cheek where you had indicated. "That's it?" she asks.

You wink at her. "Another round?" you ask in response.

Scarlett eyes you suspiciously and for a moment you think she's going to decline, but her competitiveness and overconfidence gets the better of her and she agrees. You go retrieve the darts and hand 1 to her. This time, since you had won the previous round, Scarlett steps up to go first. This time however, Scarlett throws her dart way too fast that you don't have enough time to react and freeze it in midair and by the time you activate your magic ring, her dart has already hit right smack in the middle of the bullseye. You could move it, but people in the crowd gathered around have already seen it. You're annoyed and it takes you a while to regain your cool before you decide that there's nothing you can do about it and you let time resume and go take your turn, using your magic ring to help you hit the bullseye again, ending the round in a tie as the crowd cheers loudly.

You go get the darts again for the 3rd time. This time, when you hand Scarlett a dart, she takes a few seconds to examine it. She must suspect something, even though there's no way she could figure out that you have the advantage of magic rings. When she eventually goes to take her turn, this time you're more than prepared and you freeze time right as the dart leaves her fingers. You go over to the dart suspended in the air and tilt it down before getting back to your position, and when time resumes, the dart dips and falls short of the dartboard. Scarlett looks shocked while some people in the crowd boo and laugh at her.

After she steps aside for you, you throw your dart. This time, you don't use your magic ring and just let the dart hit the board. It's not even close to the bullseye, but it's more than enough to beat Scarlett again. The crowd cheers as you turn to Scarlett and she waits for you to say your demand.
