Han Jisung had always lived in the quiet. With music as his only refuge, he drowns in melodies to escape the loneliness that clings onto him like a second skin. Despite having some friends, something is missing. Someone is missing. A presence he's only ever imagined. Then a message changes everything. A stranger named Minho bursts into Han's life with relentless energy and a strange request: "Give me a month." Minho is everything Han isn't-loud, fearless, impossible to ignore. What starts as an unexpected arrangement turns into late-night talks, quiet mornings, and a connection that feels like it was always meant to be. But a month has an expiration date. And when the clock runs out, Han is left with the question he's too afraid to ask: Was Minho ever his to keep?

Jisung had spent his whole life as an option - never a choice. Passed between parents who didn't want him, he grew up believing he was temporary. Until the Lee family decided he would be their grandson's spouse. He expected duty. He expected distance. He never expected Lee Minho - someone who would handle him sometimes patiently, sometimes frustratingly. Because sometimes love isn't loud - it's patient. Sometimes home isn't a place - it's a person. And sometimes, forever doesn't feel like a chain... it feels like a promise.

Han Jisung and Lee Felix are best friends. But what happens when Han Jisung starts to fall for his friends older brother?
