This is the previous adaptation of this story, and it’s far better. The Korean version spent like 15 mins at the end expressing what the Japanese original did succinctly and movingly in basically one scene.
They're both love stories involving people with disabilities. They're also both moving and emotional. They're also made by directors who are very serious and artistic and take chances with their work.
They're both bittersweet love stories about a handsome young man who falls in love with a tsundere girl in a wheelchair. You may cry in both movies.
Another emotionally devastating arthouse-quality movie that avoids drama cliches and involves romance with girl who has disability.
