Atlast! I finished it. The first 3 eps are confusing but as the story progresses, you'll come to understand it. At first it was running in circles but when you reached episode 4, every pieces goes on. The alley always almost got me screaming. Que horror! It was so terrifying so you should watch it with the lights on. I'll give the PR a 5 for that. What I really liked is the story of the hiker and the dog. But what surprises me is Eunsoo's acting when his mom forcedlly (?) gave her "the light". I always knew that she acts really good when I watched her in Twinkling Watermelon but, bro, she devoured it in Light Shop. And guess who is Ajussi's ttal. Anyway, I recommend watching this slowly because it will surely finish you when you binge watch it. The acting and the storyline both deserve to be slowly absorbed.
Reserve your tissues! Enjoy watching :>>
