It's the merry go round of life, it continues. You grow up, you were once a child, laughing, playing, rejoicing in your mother's arms, and if you did have grandparents, they went through what you have. You grow up, and you're now in their shoes, watching your grandchildren play, rejoicing in their mothers arms. You've tried so many things. You've loved, you've cried, you've done all sorts of things. In the past, what did your grandparents feel? Now you're in their shoes, and you can feel it. And you now regret all these little things that you've said to them, as they've only tried to keep you safe, because they want you to feel their shoes, when you're there, watching your grandchildren.

It's beautiful, isn't it. Life, it continues, a merry go round of life. In this movie's show, he loves someone, as he grows up, he cries, he misses her, as he has now spent his entire life, dedicated to her purpose.

It's amazing, it's amazing. I.. wish, I want, i'm jealous. Because he spent his entire life, searching for an answer, dedicating it to the one person he loves, and still loves. Beautiful, amazing, but it is now tranquil. He's experienced the merry go round of life. You can't resurrect someone from the dead, as his grandpa already said. They're gone. But you've come to this little world, on earth, where you're here to love it, to experience it for yourself, it's delightful, appealing.

You've grown up, haven't you?

Edit: There's another movie, this one is "To Every You I've Loved Before." (Boku ga Aishita Subete no Kimi e) and the other, "To the One Me Who Loved You." (Kimi wo Aishita Hitori no Boku e) I recommend you watch "To the One Me Who Loved You," first, because it tells the story of his childhood. The other one, "To Every You I've Loved Before," is about his growing up years. Once you watch both of them, you'll understand. The one that I recommended that you watch after has an official understanding that you'll be able to understand the entire thing more easily.
