This is a masterpiece so I had to read it again. After re-reading this, I can understand why I felt so much sadness and despair when I first read it. I cried for two days mourning the death of our beloved Kaori. But I've realized that her death is not a tragic ending, but a happy one. She had regrets, but she was satisfied. We had regrets, but we were satisfied. Indeed, I'd also like to believe that The Summer You Were There ended on a happy note. There was sadness when I first read it, but deep inside there was also gratitude and hope for them both. This was their love story, that was completed. but had never ended. Because even after Kaori's death their love lives on. What a perfect romance story, Makes you cry, Makes you happy, And even, Makes you hopeful.
PS : i only re-read the last chapter btw
