This film tells the story of two young people with terminal illnesses from the time they meet to the time they part. I tried to make the audience ignore the external factors such as times and circumstances when watching the film and just immerse themselves in the world of these two people. Society is a tolerant existence, and the process of these two people with opposite personalities, from meeting to sympathizing with each other is also the most ordinary and precious memories in life. The sea is vast, the tide rises and falls, your coming and going like the tide, along with the dawn is far away.
