Shota found himself in an enviable position that most men could only dream of. His stepsisters, Reina and Aina, had both confessed their feelings for him around the same time. What started as a complicated family situation quickly evolved into something. They willingly became “pets” dedicated to their older brother’s desires.
With Shota indulging his fantasies whenever and wherever the urge struck. The sisters, deeply infatuated, found themselves sinking further into his world. Restaurants, parks, even at home,no location was off limits as their bond grew increasingly intense and, to outsiders, increasingly bizarre.
But all dynamics shift when outside elements enter the equation.
One ordinary afternoon, Aina returned home with a flush that had nothing to do with her brother. A classmate had slipped a love letter into her locker, complete with chocolate and a confession written in shaky handwriting. For the first time, someone outside their triangle had noticed her, truly noticed her, and the attention stirred something unexpected.
Meanwhile, Shota found himself distracted during one of their usual encounters. His phone buzzed constantly with messages from a uni classmate, a girl with long hair and an easy laugh who actually shared his interest in vintage films. When Aina asked who kept texting, he brushed it off with a vague “just a friend.”
Reina watched the cracks forming with growing unease. Their perfect triangle, built on secret vows and midnight promises, suddenly felt terribly fragile. Aina kept the love letter hidden beneath her pillow. Shota’s phone buzzed at odd hours. And Reina wondered if being someone’s devoted pet meant anything when the leash could be cut at any moment.
Sometimes the tightest bonds break not from pressure within, but from the simplest temptation without.
