I'm gonna say it, but this is the best cdrama I've watched, and I've seen a lot. They chose the best actors and actresses for this and not just the main leads. The chemistry is over the roof, it's sweet and realistic. Most girls have had a crush and this plays out those feeling step by step, making you immersed in their story as if it was your own. The OST also adds feelings of longing to their relationship alongside a smooth production. I really cant recommend this drama enough if you love a sweet, gentle romance.
