You had been deeply in love with Min-kyu for as long as you could remember. Both of you had grown up struggling, finding comfort only in each other’s presence. Min-kyu had always dreamed of becoming a famous singer, and you had done everything you could to support him. You helped him financially, even funding his education at an elite school, sacrificing your own comforts because you wanted to see him succeed. Your happiness had always been tied to his.

Now, Min-kyu was living his dream. He was a member of a popular music band, adored by fans across the country. Meanwhile, you were working as a simple fashion designer, trying to carve your own path in life. But things between you and Min-kyu had begun to change. His fame made even small gestures—like walking together—impossible, and you both slowly started keeping your distance. Still, you never stopped caring. You continued to send him the dishes he loved, discreetly leaving them at the band’s club, hoping he would remember the warmth of home amidst his chaotic life.

Your efforts didn’t go unnoticed. The band members started to notice the care and dedication you put into supporting Min-kyu, but none more than Jung Jae-hyun—the band’s leader, the most famous, charismatic, and handsome member, who was also an actor. He watched you from afar, intrigued by the way you quietly cared for someone who barely seemed to notice. It made him think of his own girlfriend, who rarely showed him any consideration or effort.

Then came the celebration. The band’s latest song had just hit a million streams, and they threw a lavish party to celebrate. You arrived, hoping to see Min-kyu, only to find him standing in the crowd, completely absorbed in conversation with another woman. He laughed at her jokes, smiled at her in a way he had never smiled at you, and seemed to have entirely forgotten your presence.

Your heart sank. The woman was Mina Sue, a stunning, elegant actress. Min-kyu had often told you she was just a “good friend,” but watching them together, it was painfully clear she was much more than that. Feeling invisible and out of place, you stepped aside from the crowd. Your mind swirled with memories, regrets, and unspoken words. You found a quiet stairwell and sat there, trying to steady yourself.

Suddenly, you felt something cold press against your cheek. You looked up to see Jung Jae-hyun holding a soda, a playful smirk on his face.

“Drink,” he said smoothly, sitting down beside you. You took the soda, still dazed.

“You don’t need to put so much effort into your boyfriend,” he said casually, his tone calm and unnervingly confident. “He isn’t loyal.”

“How do you know?” you asked, your voice trembling.

“He’s cheating on you,” Jae-hyun replied simply. “With Mina Sue—the model standing next to him. And she’s my girlfriend.”

Shock froze you in place. “Wait… your girlfriend is dating my boyfriend? And you’re… so calm about it?”

Jae-hyun tilted his head, a wry smile playing on his lips. “If someone cheats, it means they were never meant for you. There’s no point in crying over someone like that.” He paused, letting his words sink in, then leaned closer. “But maybe… we can turn this around. Let’s be in a fake relationship together. Think of it as… giving them a lesson they’ll never forget.”
