This drama kept talking about parallel universes but I wonder why Jingyeom and 2020 Taeyi only time travelled to the same universe... Explanation is needed for these coincidences
I'm watching for the leads only. Their chemistry is off the roof, so so good! The plot? It's predictable, overused and cliche. Really similar to Love Designer who aired few months ago. If you have watched LD you'll able to tell 5 similarities at least. LD also isn't original, i bet you can mention hundred dramas with similar conflicts. I only mentioned LD because both are cdrama that aired in 2020 and i don't watch chinese modern drama that often. Bai Lu and Luo Yunxi are really charming, i love them so much! I have a lot of fun watching them. I don't mind with the cliche plot, as long as i find it entertaining i will keep watching <3
