Life partners Iong & Tung are a very loving couple, but their relationship is often challenged by the fact that Tung flies overseas frequently for business. As Iong finds it harder and harder to cope with the loneliness, Tung finally made it to relocate to Hong Kong. However his final flight to Shanghai never brought him back, as the plane crashes in a tragic accident. Iong tried hard to lead a normal life after Tung’s death, but it seems there are unfinished matters for him to take care of, just like the plant Tung left him that is yet to blossom.
