This 2019 short film was presented by Dust in 2022.

A woman named Lu Li kills herself because her businessman husband, Yu Cheng, is practically never home. Then Yu Cheng is given a chance to make a five-minute phone call to Lu Li within the last 24 hours of her life, but he's not allowed to try to save her life. Actually, everything he says is designed to try to prevent her suicide, but only when he specifically asks her not to kill herself is the call momentarily interrupted, so that she can't hear him. Anyway, it's a fairly simple sci-fi concept, but it's a very powerful story. Very tragic.
