This is the lowest rating I have given a drama on MDL before. This second season felt like a student film completely written, casted, and shot by students without much experience or a clear grasp on the story they wanted to portray. It is a bit disappointing that this is connected to the first season.

In the first season we are introduced to the idea of Mono's who live in a world of grey until they manage to meet someone who's face will allow them to see color, their probe. Geon Yoo never wanted to meet his probe out of fear that he may hurt that person due to obsession so when he meets Yoo Han he tries to run away. Yoo Han however does not want him to run away. Their adorable romance that stems from their connection is simple but sweet to watch. Yoo Han helps Geon Woo overcome his fear by being a stable and unmovable presence in his life. Between this unique plot, the pleasant soundtrack, and the chemistry between the pair I enjoyed the first season far more than I expected to.

The first season introduced the side plot that Geon Yoo's mother had been missing and his Aunt was searching for her while taking care of him. It also emphasizes the connection of a mono and probe, essentially soul mates, but how the colorizing of a mono's world can also feel so addictive that they become obsessed with their probe. This obsession can make the probe uncomfortable or lead to the mono doing unspeakable acts to the people around their probe or even to them. The idea that mono's are dangerous and are outcasts is mentioned often. This second season tries to expand on that notion while running with the mystery of his missing mother. It becomes a story filled with practically nothing but Monos. The previous season made it seem like Monos were there rare while this season is littered with them and they are obsessed with wanting to see color so much that they have a secret 'club' and drugs and surgery to allow them to do that.

Honestly the plot is a bit of a mess. It opens with Yoo Han having been kidnapped but for some reason it is not publicized which makes no sense given the kind of family he has that was so worried about him being kidnapped in season one. It was a convenient excuse to have the character missing as the actor may not have wanted to return. So the shows premise becomes Geon Yoo searching fervently for Yoo Han and his mother and in his search he comes across a new friend whose sister was a mono that was killed trying to get the surgery. The pair try to enter the dangerous world of this secret Mono cult to find the truth behind the missing monos and the death of his friend's sister.

Acting was amateurish in this entire cast. From no real emotion shown for the death of a sister to the creepiness of the Mono cult. Editing is also very patchy with scenes and songs cutting off abruptly. Again this is primarily a student film continuation and I would not suggest you waste your time on it. The first season was a simple watch and I enjoyed it for the chemistry and interesting and unique plot but this continuation was just a mess.
