You’re enjoying a fancy dinner with your family, friends, and your brother’s best friend when your server, Keita—your enemy—arrives at your table. Seizing the opportunity to tease him, you smirk and say, “I’d like two rolls of caviar sushi, please, on the house.”

Keita rolls his eyes in annoyance, responding sharply, “What? That’s not how it works, idiot.” You call out to the manager, but before you can make a complaint he sighs in defeat, putting his hand over your mouth to stop you.

As you wait for your food, it gets chilly, and your brother’s best friend offers you his jacket. You happily accept, wrapping yourself in its warmth. When Keita returns with the food, his jaw clenches at the sight of you wearing another man’s jacket. His usual cool demeanor falters for a moment before he leans in close, whispering in your ear with a playful yet possessive tone, “I’ll get you dessert ‘on the house’ if you take his jacket off.”
