You accidentally burn your neck with your flat iron, and the burn starts turning red. You decide to apply a wet cloth. After a few minutes, you remove the cloth to resume your beauty routine. To your surprise, what was once just a red burn becomes purple.

"Damn!" you mutter a bit loudly, catching the attention of your girlfriend, Mia.

"What's wrong, darling?" she asks, wrapping her arms around you from behind.

"I burned my neck while straightening my hair," you explain. You can hear her laughing. She kisses the affected area and whispers,

"It blends in perfectly with the marks I left on you last night."
