Detention

At Greenwood High School, transfer student Liu Yun-hsiang witnesses a shocking incident at a deserted building and runs afoul of school authorities.

After an initial encounter with Fang Jui-hsin's spirit, Yun-hsiang finds herself in an otherworldly dimension and accepts a life-altering bargain.

With Jui-hsin's guidance, Yun-hsiang finds creative expression through poetry, but her sense of self begins to falter.

As her relationship with Shen Hua stirs up suspicion around the school, Yun-hsiang struggles with writer's block and faces betrayal.

Yun-hsiang becomes a target of slander, Shen Hua caves under pressure from his father, and Jui-hsin watches Yun-hsiang carry out an act of desperation.

Yun-hsiang becomes trapped in a parallel consciousness. Cheng Wen-liang seeks his uncle's aid in preventing Jui-hsin's vengeful plan.

As his troubled past with Jui-hsin comes to light, Wei Chung-ting helps Yun-hsiang remember her own identity. Panic spreads throughout the campus.

Yun-hsiang races against the clock to free herself from Jui-hsin's time loop and urges her spirit to find redemption.
