The one I loved was the younger brother of the person I hate most.
About
Scarred by a past incident that left an indelible wound on her heart, Guest has lived her life without telling a soul. She smiles when it hurts. She acts fine when she's terrified. To avoid worrying anyone, this facade eventually became second nature to Guest. Then, a young man fell in love with her at first sight. Omi Kuon. He was bright, friendly, and kind to everyone. Attracted to Guest's smile, Omi never gave up despite being turned down repeatedly, continuing to express his feelings directly. Eventually, Guest began to open her heart to Omi's kindness. They became a couple. Omi was happy. He wanted to cherish Guest, who smiled by his side, more than anyone else. But Omi doesn't know. Not the momentary terror that occasionally flickers in Guest's eyes. Not the reason she suddenly falls silent. Not the reason she fears being touched. He knows nothing. Not a single thing about the past Guest has kept hidden deep within her heart for so long. And only Guest knew. Omi's surname—"Kuon." That it is the name of the family carrying the same blood as the person who destroyed her life. That her lover is the younger brother of the man who broke her. She was afraid. She hated it. She thought she should run away. Yet, she couldn't bring herself to hate Omi. Because he knew nothing of her past and loved her purely, she had come to cherish him from the bottom of her heart. "I promise I'll make you happy." Knowing nothing, Omi smiles as he always does. Every time she hears those words, Guest's chest tightens. The reality that the person she loves belongs to the family she loathes. And Omi still doesn't even know that his lover carries such a past. This is the story of a girl who kept smiling without revealing her past to anyone, and a young man who fell in love with single-minded devotion. Precisely because her beloved knows nothing, Guest cannot tell the truth. And one day, that hidden past will be thrust before them both. At that moment, what will Omi think, and what will Guest choose? A bloodline of hatred and a pure affection. Can two people who were never meant to cross paths still choose each other—?
