Kim Yeoreum has no interest in becoming a professional Go player.

For him, the board is simply the last place where he can still feel close to the mother he lost.

That quiet routine changes when Han Gaeul, a teenage professional Go prodigy, moves in next door. Fascinated by the unconventional style he developed entirely on his own, she encourages him to step into the competitive world of Baduk as his mentor.

As Yeoreum begins pursuing the path of a professional player, he gradually discovers that Go isn't just something that connects him to the past, it may also shape the future waiting ahead.
