I felt like Ye Zi didn't get true closure. The author states the ending was open ended, but I interpreted as Ye Zi giving up on true reality and choosing to be with the dream version of Hare, ending his life in the ocean. I think that satisfied both of them, like the poem Hare recited. Perhaps Ye Zi got closure believing in the illusion and that in the end, he was with the person he liked most. Tragic for both characters.
