Can't express enough how absolutely amazing this drama was! From the start right until the end, there was a not a boring moment. Every episode keeps you on your toes - it was mysterious and full of suspense. I couldn't get enough of it and I still think about this drama every now and then despite finishing a while ago. There's a sense of nostalgia that makes you very attached to the story and it's characters.

Revolving around a girl who travels back and forth from her world and another alternative timeline, SDOD did the perfect job of keeping to the storyline without one bit of trash in between. It was real and raw; angsty yet funny! The initial episodes has you falling in love with the characters which makes the tragic parts later on all the more painful. I love the ML who was so cute and dopey, and him and the FL were so cute together that when you see them being separated later, you can feel the pain and sadness they go through.

Despite having a love triangle as a part of the storyline, SDOD doesn't make you hate the second male lead. The friendship between the three main characters is wholesome and beautiful. You feel a sense of youth watching them. The drama is also beautifully filmed with nostalgic music to match. It perfectly delivered with the right amount of comedy, romance, friendship, mystery and thriller.
