She (you) had recently bought an apartment; it was her pride and joy. She spent a year there without expecting... the next thing.

For weeks, the girl had been obsessed with the small anomalies in her apartment mirror. Sometimes, as she passed by it, she swore she saw a glimmer that didn't belong in her room: a shadow moving where there shouldn't be anything, a cup that changed position, or a blurry figure crossing the reflection as if it existed on the other side.

At first, she thought they were tricks of light, illusions caused by tiredness or stress. But curiosity got the better of her.

She began to record the reflections, measuring angles, light, temperature. Sometimes, in the fogged-up bathroom glass, she swore she could make out silhouettes... a tall figure with dark hair and a warm gaze that seemed to be searching for something, or someone.

And then she saw him clearly. It wasn't her reflection: it was him. A boy in his own bathroom, but not hers. His version, inverted. For a few seconds, their eyes met in the mirror, and both recoiled as if they'd seen a ghost.

For several days, these fleeting encounters repeated themselves. A passing reflection in the closet door, a blurry figure in the hallway window. Neither spoke, neither understood. They simply observed each other, a mixture of fear and fascination, until one day, unexpectedly, the veil was torn away.

She had just stepped out of the shower, steam still lingering in the air, and as she opened the bathroom door, she felt something strange. Everything was the same… yet different. The pictures on the wall weren't where they should be, the room smelled warmer, and there was a steaming cup of coffee on the dining room table.

And there was Eiden. Wearing that brown jacket, his hands still trembling from the shock.

His honey-green eyes gazed at her with surprise, but without fear. He knew her—from the reflections, from the brief moments when the mirror had allowed them to see each other.

“You saw me too?” she asked, clutching the towel to her body.

He nodded nervously, trying to smile.

“I thought it was my head. I didn’t know if you were… a reflection or a person.”

His voice was soft, as if afraid of breaking something.

He took a step forward, with that natural kindness that defined him, and reached for a shirt in his closet.

“Here, put this on, you must be cold,” he said, offering the garment without breaking eye contact.

But as soon as his fingers touched hers, a vibration ran through the air.

The sound of the world faded away.

And in an instant, she disappeared.

Eiden was left alone in the room, staring at the empty spot where the girl in the mirror had been.

Unaware that in the other dimension, she had just opened her eyes in her own bathroom, his shirt still clutched in her hands. The next day dawned gray. Eiden woke with the feeling that something was off. Everything was the same… but it wasn't. The clock showed the same time, the coffee maker was ready as always, but the smell was different. Fader. More foreign. He walked to the bathroom, sleepily, and when he opened the door, he froze.

Steam filled the room. There were towels that weren't his, bottles with names he didn't recognize.

And in front of the mirror, with damp hair and wearing a light robe, there she was.

The same girl from the reflection. The one who had disappeared the night before.

His breath quickened, their eyes met through the fogged glass. She took a step back, he took a step forward.

"Again?" she whispered, incredulous.

"I don't know," he replied, with a nervous smile. "But… I think this time I'm the one who got involved where I shouldn't have."

She let out a small laugh, a mixture of shock and relief.

"This doesn't make any sense," she said, looking at him like someone analyzing an impossible equation. "It's not normal teleportation, there isn't enough energy... and you shouldn't even be here."

"Well, I thought the same thing last night when you left me talking to myself with a towel and a cup of coffee," he joked, shrugging.

Despite the chaos, there was an eerie calm between them. As if their presences balanced each other out. He, with his awkward but warm smile, and she, with her brilliant mind searching for logic in the impossible.

The following days became an improvised routine of encounters and disappearances. Sometimes she was the one who crossed over. Sometimes he was. Sometimes they only saw each other's reflection in the hallway mirror, or in the glass shower door. The universe seemed to be playing with them, pushing them to meet for no apparent reason.

She began to experiment with precision: She noted the time, the light, the temperature, even the mirror's position.

Eiden, on the other hand, simply appeared when she least expected it and sipped coffee while she took notes.

"Aren't you scared?" she asked him once.

He shrugged, sipping his coffee.

"A little. But if all this means I'll see you again, it's worth it."

She pretended not to hear him, but a smile escaped her.

So they both began to communicate and talk more. Eiden, a calm, relaxed Golden Retriever, shone with affection. At the same time, he needed physical contact and wasn't as good at math as she was. He was more artistic and worked as a barista. But she was very intelligent, fascinated by quantum science and quantum physics. She was quite smart but also very antisocial. She was quite serious and worked as a secretary. At night, she liked to fight illegally, earning more money than she could afford.

Over time, she began to notice something: every time they touched, the rules changed.

At first, a mere touch was enough for one of them to disappear.

But then, after so much trial and error, something shifted.

One day, while they were arguing about which dimension was the original, he accidentally brushed against her hand… and nothing happened. The air didn't vibrate. There were no flashes.

Nothing.

"Why not…?" she whispered.

He looked at her, and for the first time, he didn't smile.

"Maybe the universe has already given up," he said, almost in a whisper, trying to be positive.

She obviously began to get anxious, pacing around his apartment while looking for something. She touched him, hoping to change things, but he began to calm down while also looking for something, but more calmly.

And suddenly they saw that mirror in the living room, that mirror she had already noticed. It was in the same position as her; it was the only thing, the only objective. Now the mirror reflected her dimension, her house.

With me and uncertainty, she began to cross through the mirror. It was no longer a normal mirror; it was the portal from her dimension to his. It was a door...

Time passed, but that door never changed. They no longer teleported; they never teleported like before. Now they could pass through the mirror. Little by little, they began to gain confidence and became very good friends, too good friends...
