Wei Yihang (played by Jackson Yee), a cancer-stricken boy who claims to be able to “see the future”, meets Ma Xiaoyuan (played by Liu Haocun), a cancer-stricken girl who believes “parallel worlds”. Standing on the terrace and looking into the sky late at night, the two of them unfold their depictions of the beautiful world to which they aspire. Centred around two sets of life trajectories of two families fighting cancer, the film depicts a warm and realistic story, and it leads the audiences to consider and face the ultimate problem that every ordinary person may face: the only thing we should do when death may come at any times is to love and cherish what we have. Life can be quite hard sometimes, but hopefully, every brave person whio fights against the odds and fate will get a little red flower as an award.
