Honestly, I didn't expect much from this drama. I thought it was going to be an extremely dramatic telling of a cliche story about a guy who repeats the same day. I didn't even like the female lead at first either, I honestly just cam to see Myungsoo's pretty face. However I was pleasantly surprised and caught off guard by some of the plot decisions. The female lead became the complex character I wanted her to be in a way I hadn't imagined it happening. For a short drama it turned out to be a really good watch, there were no useless episodes, and it had my feelings in a twist by the 3rd episode. ALSO if you don't like a bit of cliche romance in general, then don't watch it, its a drama for crying out loud, it will almost always be a little cliche or dramatic.
what it lacks:
the acting in this drama wasn't PERFECT, but who really is you know? I would definitely say the acting was good, sometimes even great. and as for the script, there weren't any supper cringe worthy lines or anything, also there were some surprisingly funny moments from minor characters and our male lead.
There are some tiny details in the show that don't get fully addressed, but hardly enough to dissatisfy a viewer.
Honestly with a little bit of tweaking this could've been a 10/10 drama, but for now 8 thirty minute episodes isn't too risky of an investment to try out a decent show.
