Storyline

He Zhengyu, a cold and arrogant lawyer living in 2022, moves into an older apartment complex and discovers a strange time-space phenomenon that connects his apartment with the previous tenant from four months earlier in 2021. Every night from 10:06 to 10:52, He Zhengyu and Chen Jialan, the former tenant, become involuntary roommates. When He Zhengyu learns that Chen Jialan knows Jiang Shenghao, a person connected to one of his clients, he seeks her help. Together, they use the time-space anomaly to their advantage, hoping to alter events in 2021 and change the future.
