It's understandable. Things fluctuate and as time goes by, more people must have watched and catched up, and therefore had rated. I'm one of those who don't rate shows until I finish watching all episodes.
Love it. Altho some thing don't make sense like how can a song be connected to the eye lol, but it was just minor thing. Love that Jung Hae In is getting great materials with DP and this, he no longer stereotyped in my mind as someone who only does romantic shows.
I think they could have let go the whole romantic angle between the ML and FL. It was unnecessary and took away the time to explore other things.
The whole markmaship of Ok Chan Mi was also, I think, weakly used. I guess, it was important plot point half way through the series when she confronted Soo Heon. But I felt like there could be more to it. Jae Boom trying to learn markmaship was also felt 'weak' too. The whole setting up on the start of the series fell off somehow. I just think it could have been used more in the series.
Is Jae Boom twin REAL or not? It seems that it was real, but at some point I felt he was delusional? Did O Sung knew or have been friends with Jae Boom's twin? Who else see the supposed actual DEAD twin?
The gay storyline was obvious. And the overly obsessiveness of O Sung and Jae Boom was kinda suspicious. Could have explore more, and could have gave a more solid reason to the plotline.
Soo Heon took a lot of blow in the head. And he is still ALIVE with his condition?
Jae Boom fell from building alive. And yet the other two died immediately? LOL. Jokes.
I liked what they did with the ending. I thought they are going to bait for second season. I'm glad it was resolved. And I like the ending quote - when everyone told the same lie, it becomes the truth.
I still can't over the fact that the workplace is so goddamn dark, it was so hard to see things in the cinema where I watched the film. Then I chuckled when Lyra exclaimed, a brownout happened.
ajung and the pregnancy and the hidden boyfriend thing is kinda suspicous like she way too calm abt it and planning…
I felt like writers won't put that in for no apparent reason. In a short series, I feel like they are somehow connected to the big plot. A possibility is that she knows everything or a lot more, and that hidden boyfriend is probably playing on SJB (misplacing key, etc). My suspect is SJB.
K-Drama 
I don't know how realistic this is in Korea, but I hope it is not. Gawd, high schoolers are awful.
