PART 1

At the Hotel Casa Virreyes, in the heart of Puebla, the grand ballroom was aglow with light, flowers, and the vibrant sounds of mariachi music. The air was thick with the weight of nearly 180 guests, intricately set tables, golden candles, and a dance floor where everyone pretended to be perfect.

But Lucía Aranda's gaze wasn't on the decorations.

It was on her brother's hand.

Ramiro Aranda had sneaked up to the main table with his signature crooked smile, the one he'd used since childhood to break things and then convince everyone it was Lucía's fault. As the photographer asked the happy couple to turn towards the camera, Ramiro leaned in, covered Lucía's glass with his jacket sleeve, and let a white powder fall into the champagne.

Lucía saw it.

She didn't scream.

She didn't fling her glass.

She didn't make a scene in front of everyone.

She felt her heart sink into her stomach.

For 29 years, her family had taught her to swallow it all: Ramiro's jokes, his lies, his debts, his blackmail, his 'it was just a joke, don't be so sensitive.' Her mother, Doña Elvira, would always say the same thing:

'Oh, Lucía, don't be dramatic. You know how your brother is.'

Lucía knew exactly how her brother was.

That's why she smiled.

Her husband, Mateo, touched her hand under the table.

'Are you okay?' he whispered.

Lucía forced a bigger smile.

'I'm fine, love.'

In that same motion, she placed her glass over his, took his, and exchanged them with a swift, silent move.

It was quick, clean, almost invisible.

Ramiro glanced at the glasses just in time to see Lucía's now-empty one, but his wife, Brenda, yanked him away.

'Come on, my love, we need a photo with your parents.'

When Ramiro turned back, Lucía held the clean glass, and the tainted one sat in front of him.

Ramiro raised his glass.

'Cheers to Lucía,' he said loudly. 'My little sister, always trying to be good, always crying about everything. I hope tonight she learns that not everything is won by whining.'

A few cousins let out awkward chuckles.

Mateo's smile faltered.

Don Ignacio, Lucía's father, looked down, as if he hadn't heard a thing.

Lucía kept her eyes on Ramiro.

'Salud,' she said.

Ramiro drank everything.

To the last drop.

Then he leaned into her ear and whispered:

'Congratulations, sister. My surprise is on its way.'

Lucía brought her clean glass to her lips.

'What excitement,' she replied.

Thirty minutes later, Ramiro was no longer smiling.

First, his tie came undone. Then he rested a hand on the dessert table. Sweat beaded on his forehead, despite the air-conditioned chill.

Brenda frowned.

'Ramiro, what's wrong?'

'Nothing,' he said, dragging his tongue. 'I'm fine.'

But he wasn't fine.

He tried to walk to his father but tripped over a chair and sent a tray of glasses crashing to the floor.

The mariachi stopped playing.

Everyone turned.

Ramiro wanted to speak, but all that came out was a broken sound.

Lucía looked at the empty glass next to her plate.

Then at her brother, who was starting to lose his balance on the dance floor.

'I think your surprise arrived before mine,' she said.

Ramiro opened his eyes with terror.

And for the first time in his life, Lucía saw her brother afraid of her.

Then he fell to his knees in front of everyone and, before passing out, managed to whisper a phrase that left the entire ballroom frozen:

'You... should not have switched the glasses.'
