My Brother Stole My Fiancée on Our Wedding Day. I Spent a Year Ruining His Life, Only to Realize I Was Becoming Him.
Undercover in the Lion’s Den
The fluorescent lights of the logistics warehouse hummed with a headache-inducing frequency, a sound I had learned to ignore over the last six months. My hands, once accustomed to signing project approvals, were now dry and cracked from handling shipping manifests. I wasn’t Hiori Arai here. I was ‘Hiro,’ the quiet temp in accounts payable who never complained about overtime.
It was a humiliating step down, career-wise, but the vantage point was worth every yen I wasn’t making.
Yoshiki’s startup, ‘GoalPost Ventures,’ was a client. A sloppy one. Through the digital cracks of my employer’s invoicing system, I watched my brother bleed money. He treated corporate accounts like personal piggy banks—dinners, hotels, ‘client entertainment’ that looked suspiciously like jewelry purchases. He was drowning, and I was the silent tide rising to meet him.
“You look like you’ve been eating instant ramen for a decade,” Fuko said, sliding into the booth opposite me.
The diner smelled of stale coffee and frying grease, a sanctuary for the exhausted. Fuko looked out of place in her sharp blazer, a stark contrast to my worn hoodie. She slid a manila envelope across the sticky laminate table. It was heavy.
“Did you get it?” I asked, my voice dropping to a whisper.
She didn’t answer immediately. Instead, she tapped a fingernail against the envelope. “You know, Rita thinks this is getting too personal. He says we have enough for a lawsuit regarding the stolen wedding funds. We don’t need to go nuclear.”
“The money isn’t the point, Fuko. Open it.”
She sighed, the sound sharp with disapproval, but she opened the clasp. Photographs spilled out.
My breath hitched. I expected anger, maybe jealousy. I didn’t expect the sudden, cold plunge of pity that quickly curdled into satisfaction. There was Chinatsu. She was standing outside a boutique, laden with bags, but her face was gaunt. The light had gone out of her eyes.
In another shot, she was sitting alone at a cafe table, staring at a phone that clearly wasn’t ringing. She looked expensive but discarded, a trophy left on a shelf to gather dust.
“She looks miserable,” Fuko murmured, watching my reaction closely. “Yoshiki is parading her around at events, but according to the neighbors, he’s barely home. When he is, they fight. Loudly.”
I traced the edge of a photo where Chinatsu was wiping her eye. “He’s bored of her. He never wanted the girl; he just wanted the victory over me.”
“There’s more,” Fuko said softly. She pulled out a final sheet of paper. It was a transcript of a text thread. “He’s seeing someone else. A receptionist at his gym. It’s been going on for three weeks.”
The revelation sat between us, heavy and toxic. My brother, the golden child, cheating on the woman he stole on her wedding day. It was almost too perfect. It was a script written by his own narcissism.
I pulled my phone out. My thumb hovered over the screen. I still had Chinatsu’s number blocked, but I could unblock it. I could send her an anonymous tip right now. He’s cheating. Get out. Save yourself. It was the decent thing to do.
It was what the old Hiori would have done—the Hiori who checked under the bed for monsters, the Hiori who forgave.
I typed out the message: Ask him about the receptionist at the gym. Don’t let him lie to you again.
The cursor blinked. One tap. That’s all it would take to give her a parachute.
Then I looked at the photo again—the designer bags in her hands. The bags bought with the money we had saved for our house. The ring on her finger that replaced the one I had spent months paying off.
If I told her now, she would leave him. She would salvage some dignity. The crash would be soft.
I didn’t want soft.
“Hiori?” Fuko’s voice was cautious. “What are you doing?”
“Nothing,” I said.
I held down the backspace key. The letters vanished one by one, erasing her chance at an early escape. I wanted her to stay. I wanted her to be there when the debt collectors came, when the reputation crumbled, when the illusion shattered completely. I wanted the fall to break them both.
“Authorize the bug in his car,” I said, my voice steady, devoid of the tremor I felt in my chest. “I want audio. High quality. If he’s bragging about the affair, I want it on tape.”
Fuko pulled the envelope back, her eyes searching mine for the gentle man she used to know. She didn’t find him. “You’re enjoying this,” she stated, not as a question, but as a sad observation.
I took a sip of the bitter, lukewarm coffee. “I’m just balancing the books, Fuko. Just balancing the books.”
