I'm not sure how to explain it, but it is such a beautiful movie. I don't think I regret watching it. I was kinda worried when I realized the pace of the romance was too fast. But I think I was wrong, this story is not only about their lovey-dovey, but it is also about how they perceive grief, memories, attachment, and admiration. How they portrayed and mixed joy and sorrow was really heartbreaking, yet heartwarming at the same time for me. Each character shows so much pure emotion, especially for both of the main characters. I love how pure their interactions were when they were singing the soundtrack in the movie. The visual animation is also really uniquely stunning. The story and each character are also well written. The soundtrack was amazing, and it was really memorable.
