Taehyung, 30, has given up on love and decides to build a family of his own by adopting a three-year-old boy. Everything is perfect-until his toddler meets their obnoxious next-door neighbour, Jungkook. The two men can't stand each other, but the toddler absolutely adores Jungkook. There's just one tiny problem. He calls him Mama. And somehow, the little boy is determined to turn his single dad and his least favourite neighbour into a family.

They were once inseparable-until one mistake tore their friendship apart. Years later, fate reunites them as CEO and assistant, where old wounds collide with lingering feelings. But after one drunken night changes everything, they're forced to face the past they left behind... and a future they never saw coming.

Jungkook struggles with haunting memories and a reality that feels increasingly hollow, while Taehyung and their son try to anchor him to warmth and love. Amidst uncertainty and hidden fears, the line between what's real and what's imagined begins to blur.
