I started watching this just yesterday and have successfully binged all 9 episodes that have come out (with the 10th one on its way today (who cares about studies)). Throughout this, I was kicking my feet, giggling like a schoolgirl, so invested that I forgot that sleep is a biological need. Nevertheless, I thoroughly thoroughly enjoyed it. Warning: it will make you feel very lonely if you are single (because it happened to me too). Even though Hye Yoon looks like she is getting typecast after her role in Extraordinary You (but I know she is a very versatile actor), I still enjoyed her character in this! Woo Seok on the other hand I've not seen enough of since 20th Century Girl (brb crying) so it's always a pleasure to see him and hear him. My only concern is if he is a good actor, which will not be established until I see him in a few more roles. Right now, he is decent and will make you fall in love with him (but I attribute that more to the character and how well Woo Seok has portrayed it - the role really suits him (I haven't watched Strong Girl Nam Soon so don't come at me)). The drama is also a pleasure to watch because all of the cast is so good-looking! But seriously how are you scolding someone for not sleeping/having dark circles under their eyes when I can see that their skin is shining brighter than my future???? Enough nagging. They do discuss heavier themes which I always like but it's more a swoon-worthy drama than a slice of life. You will not regret watching it. Fingers crossed for a happy ending!!
