Lee Sangwon is an altar server. Born in a strict religious family that believed love was solely for the opposite gender. Every feeling in his heart was called wrong, every desire a sin. Yet he could not stop caring for Lee Leo, the son of a powerful political family, expected to lead, to never bring shame to his name, and to protect his family's legacy above all else. Sangwon knew from the beginning that being with Leo would put everything at risk. His family would condemn him, and Leo's life and future could be destroyed. So he made the choice that broke his heart. To keep Leo safe, to protect the love they had, he stepped back and let him go. "The world will never forgive us if they see me by your side." "You call this protection? Baby, it is killing me."

Leo and Sangwon were once trainees who lost their chance at debut- but never lost each other. After years of exhaustion, they reunite on a survival show and rise to fame as the leader and center of Alpha Drive One. Beneath the bright lights and growing success, they hide quiet feelings neither dares to confess. Between Quiet Hearts follows their journey from a tiny shared apartment to global stages, exploring unspoken love, second chances, and the bond that never let them go.

When Leo, the quiet dreamer with walls around his heart, crosses paths with Sangwon, the boy who shines like morning sunlight, a story of unexpected warmth begins to unfold. What starts as simple banter soon deepens into late-night talks, unspoken feelings, and a bond that feels both terrifying and inevitable. Together, they learn that love isn't always loud, it's in the small glances, the comfort of silence, and the promise of "I'm here" when the world feels too heavy. Leowon isn't just a love story, it's a journey of healing, trust, and finding a home in someone's soul.

Sangwon, under the hacker name SweetByteBaby, walked straight into the life of the assassin, Lee Leo, the assassin sent to kill him. He approached Leo with soft smiles, gentle touches, and words that felt trustworthy. He acted like the perfect lover, drawing Leo closer while keeping his true identity a secret. Every kiss was part of his plan, every sweet lie a step toward survival. For Sangwon, it was control hidden in tenderness. For Leo, it felt like love, even though it was part of the hunt. Leo enjoyed every moment. The voice that had teased him through the screen now whispered his name in the dark, soft and trembling against his skin. He let Sangwon play, let him think he was in control. But every kiss left a mark, every touch claimed him, and every breath pulled Sangwon closer. In the end, Leo didn't just want him. He owned him. "I told you, Baby. Once you're mine, you stay mine." "You should have known, Leo. I never stay."

Enemies. Partners. Something more. Leo is the golden boy of the university - effortlessly popular, charming, and hiding the kind of family secrets that don't make it into Instagram posts. Sangwon prefers silence to small talk, deadlines to drama, and solitude to social events. They never planned to speak. They definitely didn't plan to be paired for a semester-long group project. But when late-night studio sessions turn into soft glances, and shared playlists say what words can't, the line between rivalry and something more starts to blur. Sangwon hums when he's focused. Leo listens like it matters. And neither of them is ready for what happens when walls start to fall - one song at a time.

Two names. Two families. One unshakable rivalry. Lee Leo had been raised to win-every move, every word, every breath crafted to carry the weight of his family's empire. Cold, composed, untouchable-he was the heir everyone feared and respected. Lee Sangwon was the opposite-wild, sharp-tongued, and unafraid to challenge the world. He was the storm that threatened to ruin the perfect order Leo lived by. For years, their hatred burned like a silent war, each encounter another battle in an endless feud. But when an unexpected business merger binds their families, the two heirs find themselves chained together by duty. What begins as venom in their words and fire in their glares soon turns into something neither of them can control. Desire. Longing. The kind of love that could destroy them-or set them free. Because in a world where bloodlines dictate destiny, Leo and Sangwon must decide if they'll remain enemies... or rewrite their legacy together.
