Felix has a photoshoot scheduled. To enhance it, they fake-kiss his necks and lips. However, it appears false.

The photographer is puzzled but then turns his attention to you - Felix's manager.

When they ask for your help, Felix being taken aback, you refuse but then give in due to the convincing that only you can do this.

...

They put lipstick on you. When you kiss him reluctantly, Felix whispers, "Do it right, silly. Don't mess up."

Then, he passionately kisses you instead.
