First, ignore the mdl summary; bears little resemblance with what’s actually on the show. The only things that got right are the fact that it deals with five different stories and that each one contains a “mystery” to solve.

Second and most important, there’s a HUGE disconnect between episodes 1 and 6 and episodes 2 to 5; which made it hard for me to really like this drama at first.

Basically, episode 1 (and its conclusion in episode 6) is about two classmates who never interacted before but find themselves sharing the same empty train; both are able to see past each other's mask and end up teaming up to solve the heinous crime against one of their classmates. This episode goes dark so I expected the same for the rest of the show, as a result I spent every minute of episode 2 waiting for something sinister to happen, but it's just the story of three childhood friends who meet to discuss the design for their class t-shirt. That’s all. There’s a little “mystery” going on but it’s very much an ordinary story, there’s some teenage angst but it has this warm, comforting vibe overall. Episodes 3 through 5 follow this same pattern:

-ep 3 is about two boys and their unrequired crushes

-ep 4 two estranged siblings manage to reconnect with a little the help from one of the fluffiest cats ever

-ep 5 is about two girls (the class president and the class outcast) finding common ground in the last day of their high school life.

In short, episodes 1 and 6 fall very much in the investigation/crime genre, while episodes 2 to 5 are very much slice of life/ coming of age stories.

At first I really struggled with this drama but then I re-watched it and liked it better the second time around, maybe because I knew what to expect so I was able to appreciate each of the stories more.

Finally, the outro of each episode deserves a special mention, as it shows behind the scenes with the actors posing for the cameras or just goofing around on set, which was super cute ^^
