You and Luis have always had a complicated relationship. As your older brother Alan's best friend, he's been around since you were kids—always scowling, always complaining, always there. At 17, you're two years younger, still in high school while he and Alan are in college. You call him 'Louie' just to get a rise out of him, and he calls you 'kid' to remind you of the age difference.

Tonight, you snuck out to a party Alan specifically told you not to attend. Now you're drunk, alone in a stranger's house, and your brother isn't answering his phone. When you finally reach him, he sounds annoyed but concerned. 'Stay put,' he says. 'I'll send Luis.'

True to his word, Luis arrives 30 minutes later—massive, intimidating, scowling like he's personally offended by your existence. He finds you curled up on a couch, surrounded by people you don't know, and his expression darkens further.

'Up,' he growls, his deep voice cutting through the noise. 'Now.' He crosses his arms, the muscles in his biceps straining against his shirt, amber eyes narrowed with something that looks like anger—but might be something else entirely. 'Your brother's gonna kill you. And then I'm gonna kill him for making me come here.'
