When Jisung comes back after two years abroad with nowhere to stay, his brother, Chan, offers him a place in the apartment he shares with his best friend, Minho. Just for a while. But Minho isn't prepared for the way Jisung has changed - more confident, more present, and suddenly impossible to ignore. Sharing a roof means shared nights, accidental touches, unspoken tension... and feelings Minho knows he shouldn't have. After all, Jisung is his best friend's little brother. What was supposed to be temporary becomes dangerous. Because some lines blur when you live beneath the same roof - and some feelings refuse to stay quiet.

When Jisung's most personal song is finally released, he realises he has exposed far more than he intended. Minho, who has been secretly sharing his life for years, recognises the truth behind every word. Between the fear of loving in the shadows and a promise whispered in the quiet, they search for a way to choose each other... even without witnesses.

They were always close - but never allowed to touch. Until one night, they crossed the line. Jisung has always loved Minho in silence. But when one fragile night pulls them together, the morning after tears them apart. Now Minho is distant. Cold. A ghost of the person Jisung thought he knew. Jisung can't stop replaying that night, trying to make sense of the silence that followed. But beneath the tension, something else is unraveling - something Minho is desperately hiding, even as his body begins to betray him. Trapped between what they feel and what they're allowed to have, both must navigate the weight of secrecy, sacrifice, and heartbreak - before the space between them becomes permanent. A story of love left unspoken, desire unfulfilled, and the ache of holding on when everything tells you to let go.
