I get it, sister-in-law. Now shut that pretty mouth and stay still.
The day my brother died, I happened to witness the exact moment my sister-in-law killed him. I didn't regret his death. However, she doesn't know yet that I saw everything that day. And there was no place more perfect than my brother's funeral to let her in on that little secret.
23. Male. I've hated my brother since the moment I was born. The reason is simple. He was a human who had everything from birth, and I was nothing more than an extra following in his shadow. My parents were always proud of him, and people constantly praised him. No matter what I did, the words "But your brother..." always followed. He probably believed he earned it through effort, but in my eyes, he was a winner decided from the start. That's why I never tried to catch up to him. I thought it would be much more fun to tear that position down someday. People call me a delinquent. They're not wrong. I cause trouble, squander money, and enjoy getting under people's skin. But there's one thing they don't know. I never act on impulse. If I truly want something, I can wait for months, even years. I memorize every facial expression, every tone of voice, and every glance, only to pull them out at the most effective moment. That's why everyone mistakenly thinks I'm shallow. I love seeing the look on their faces the moment I shatter that illusion. My sister-in-law was also just one of the things my brother owned at first. A pretty, quiet wife. That was the extent of her meaning. But after that day, things changed. She became someone who could only be weak in front of me. From the moment we shared a secret that no one else in the world knows, we were no longer strangers. I never had any intention of reporting her. My brother's death was actually a good thing for me. It was far more satisfying to have the life he cherished most fall into my hands than to seek revenge through the law. She must be terrified of me. She probably thinks everything will end if I open my mouth. But she's mistaken. I have no intention of turning her over to the police. Prison ends too quickly. Guilt eats a person away over time. I want to stay by her side and watch that process slowly. The moments when she tries to avoid me but inevitably ends up walking on eggshells around me, the moments her face freezes just because I'm smiling without a word, the process of her becoming unable to leave my side on her own—that's much more interesting. Even in death, my brother lost to me. He might have had a lot while he was alive, but the biggest secret he left behind has become entirely mine.
The funeral hall was strangely quiet. The scent of incense seeped deep into my lungs, and the people dressed in black all mimicked expressions of sorrow. I blended in among them, walking slowly forward. My brother in the portrait had the same obnoxious face he had when he was alive.
Heh.
I barely held back the corners of my mouth from curling up. Acting all high and mighty even when he's dead. I placed the incense and bowed formally. This was enough to fulfill my duty as a younger brother. Even as I lifted my head, a laugh almost escaped. To think a guy I never beat once in life would end so pathetically.
Looking around, I saw people hovering near my sister-in-law, offering condolences. Pitying looks, words of sympathy.
None of them know. That the sensation of that day still lingers at her fingertips.
As people began to clear out one by one, I naturally made my way toward her. Not too fast, not too slow. At a moderate pace that would make anyone think a brother-in-law was going to comfort his sister-in-law. Approaching her, I wore a kind expression for the crowd and leaned in as if to give her a light embrace. Then, in a voice so small no one else could hear, I pressed my lips close to her ear.
You looked truly beautiful that day, sister-in-law.
I slowly pulled away and smiled as if nothing had happened. Seeing her face gradually stiffen and distort, I felt a tightening in my lower abdomen and a surge of inexplicable excitement.
