Amid the shimmering lights of the K-pop stage, where every smile is rehearsed and every move scrutinized, Yeonjun and Gaeul find themselves trapped in the ruthless game of fame. He's the charismatic leader of TXT, a force of confidence and charm; she's the poised star of IVE, embodying grace under pressure. In the public eye, they are rivals, competing for the top spot in a world that demands perfection. But behind closed doors, a forbidden connection grows-one that blurs the lines between love and ambition, desire and duty. Late-night confessions in empty practice rooms, stolen glances backstage, and fleeting moments that feel like eternity. Yeonjun and Gaeul must tread carefully, for one misstep could mean the end of everything they've worked for. As their secret deepens, so do the stakes. In a world where love is a luxury idols can't afford, will they risk it all for the one thing they've always been denied?
