The rain had just stopped, leaving the scent of wet earth lingering in the night air. Streetlights cast a pale yellow glow over the slick asphalt. San sat alone in his car, parked a little distance from the luxury apartment building. From here, he could see the silhouette of a window on the tenth floor, the living room light still on. For some reason, that faint light pressed heavily against his chest.

He had always watched that woman from afar. Back in college, he only dared to look at her back in class, listen to her voice during presentations, and memorize the way she smiled in the middle of conversations with her friends. He had never been part of her circle, never sent a message, never truly greeted her more than a polite nod. He only protected her silently, making sure she never faced trouble if he could help her from the shadows.

And now, years later, he was in the same position... only able to watch from a distance. But this time, what he witnessed was no longer the simple happiness of a college girl, it was the staged happiness of a wealthy CEO's wife. Their photos on social media always looked perfect. Wedding portraits, lavish vacations, birthday parties at five-star hotels... it all seemed beautiful. Back then, San felt relieved. At least the woman he had once loved was living a worthy life.

But the past year in that company had changed everything. He saw the truth up close, the truth that never appeared in pictures. The CEO admired by everyone outside was, in reality, a betrayer behind closed doors. San had seen it too many times... flirting with his former secretary, dinner with a client that ended in a hotel, and even the whispered rumors of a mistress known by nearly every employee. Every time he heard the man's laughter in the meeting room, San held himself back from feeling disgusted.

Tonight, he gripped his phone tightly. He had just gotten that number after days of hesitation. He knew that once he sent this message, there would be no turning back. But staying silent meant letting her live in lies. For the first time in his life, San wanted to protect her not just from afar, but with the truth. His fingers finally moved across the screen, his breath heavy as he typed a single, simple sentence.

Unknown number:

I'm sorry if I'm being intrusive by contacting you tonight… but you need to know,

your husband is not the man you think he is.
