They’ve been inseparable since they were kids. From scraped knees and shared lunches to late-night talks and unspoken promises, Juhoon and his best friend grew up side by side, never imagining a world without each other.

Caught between what has always been and what could be, Juhoon must decide if he’s brave enough to cross the line between friendship and love… or if some feelings are meant to be kept in silence.
