How Long Will I Love U 超时空同居 tells of the bickering relationship between neighbours who live in parallel timelines, who end up pretending to be a couple. A woman from 2018 (Tong Liya) wakes up to find her wall has disappeared, and discovers her new housemate is a man from 1999 (Lei Jiayin). Cue hilarious cohabitation hijinks and friendly bickering.

Produced by Xu Zheng (Lost in Thailand / Hong Kong) and directed by Su Lun (Lips and Soul), the film is scheduled for a May 18 premiere.
