As always KBLs come trough with their cool concepts and story ideas, but the execution was really bad. Part of the reason I really like south korean storytelling in tv shows is that they always think of interesting combination of characters from different backrounds. However, starting from the confusing timeline to repeated, non-sensical dialogue, putting the same song literally every 10 minutes, the long lasting close-ups of actors staring into nothing... it looked very diletant, like someone's homework from the final exam in movie school.

The acting was not bad at all, and I think the actors could've done more if someone actually read through the script and made it more like normal people talk and behave, it felt a bit theatre-like in its presentation, where people had endlessly free time to continuously met in coffee shops for "serious" discussions.

The two songs that they played ad nauseum, where not so bad and I would add them to my youtube playlist, but playing them constantly really just drove home the fact that they probably put all their money on producing these two songs.

it is ok for a one-time watch, there is very little rewatch value, unless you enjoy awkward kisses, and even more awkward sex scene.
