I liked it from the very beginning although I admit there was some parts of the drama that dragged, particularly towards the end, it kept me engaged. I like the concepts of soulmates and this story had it. I was rooting for them to be together after all they had suffered in their past life. Yes the ending is not satisfactory at all but in this case the journey matters more than the ending: good or bad. Honestly tho the drama could have done without all the filler but hey what can we do? I liked the acting from both the ML and FL. FL gets a lot of flak but honestly, I've seen much worse than her. For me she did a good enough job.
And I did think she had good enough chemistry with the ML. The comedy was spot on and tbh that's what I enjoyed the most about Kokdu next to the ML's acting he did a good job basically playing three characters. Yes this could have been so much better but I liked it and it is one of my faves of 2023 so far. In that case I give it an 8.0 out of 10.
