In the mist-shrouded country of Tilos, Shi Jin could hear the whisper of the clock tower ticking late at night since she was a child. Legend has it that every echo of the bell tower contains a secret word of time that is unknown to the world. In order to pursue the truth behind her father's mysterious disappearance, Shi Jin stepped into this magical clock tower that floated between time and reality, but unexpectedly got involved in an ancient gambling game about "time atonement". Under the clock face, the reflection of time lingers, and memories turn into whirlpools, trying to swallow up the intruders one by one. Shi Jin must solve the mystery of the clock tower owner and reveal the true will behind time in order to make a choice between destiny and self. The night in the mysterious country is like ink, and what flows between the gears is not only minutes and seconds, but also forgotten oaths and choices. Every time the bell rings, it is a questioning of the meaning of existence - and can Shi Jin find her own exit in the maze of time?
