The concept of this story is definitely original, but I wouldn't consider it too outstanding.

Long D definitely has an original concept, but it doesn't stand out much. The story is about a couple in a long-distance relationship, which is interesting. It shows the ups and downs of being far away from someone you love and shows how technology can both help and also complicate relationships.

The characters are decent, but their chemistry feels a little flat. The main characters don't feel as connected or as deep as you might hope for in a romance drama. While the themes of love and personal growth are important, the show doesn't explore them in an exciting way. The pacing can also feel slow, and some parts of the story is predictable.

Overall, Long D is a good option if you're looking for something simple, or slow paced, but it may not be the most memorable or exciting drama. It's okay, but if someone asks me if it was good, I wouldn't say it was.
