This is one of the rare gems that not only gets people hooked on K-dramas, but it's also nearly perfect. The plot is a bit like Back to the Future mixed with That Thing You Do, but it's more intricate, interesting, heartfelt, and compelling. It goes beyond the common tropes we see in time travel stories and delves deep into the heart of struggles of the deaf community in a beautiful way that anyone can relate to. The characters and relationships in this drama are so rich and moving that they'll stay with you long after the last episode.
