It's another Korean mini BL series. I mean, WHY? The plot about a mono and a probe is interestingly new and very promising. It could have been a great way to play with the story if it was in regular full-length series. So what happened was it became obviously shortened with many gaps and other angles not given a shed of light, leaving the viewers many questions in mind. I wish a bit more background was given about the early days of having color blindness and face blindness for both of the main leads. What about the progress of the search for the mom who was a mono, too? What really happened the day she went missing? What was the images about her underwater? I guess this is the result of having the series short. But it also gives us a hint of a very big possibility of having seasons.

Korea joined the BL world by starting short series with different main leads. It's good that they are giving chances to other actors to show their potentials and each drama recently released were given justice. I just hope that they won't end in just one series but take this as a starting point to have more projects like in Thai BL where the main ships were given series of projects.

The actors in this series can be considered reasonably good. Perhaps they were originally idols and not actors. If given the chance to do more projects though, I believe they'll do it better. Practice makes perfect, we say. But the chemistry is really effective.

Again, I hope there will be a next season and all questions that were left unanswered be cleared then.
