This one has an interesting Setting in a alternative World, where Colourblinds (monos) only can see Colours with one special Person( their Probs)and become obsessed with them...
so the idea is great,just as the side stories like the lost mother, the ghost of the grandfather and so on.
I’m looking forward to a second season to see if this stories are cleared up.

In the first Epsiodes i don’t get the Character of Go Yoo Han, he reminds me of a manipulative Drugdealer (with far too much make up!),who only uses the poor Choi Wee for his own pleasure.
But the Twist in the End makes sense. As well as the commited Suicide of Choi Wee, which suits perfectly to his Character.

So all in all it’s a good series.
But unfortunately the BL-Aspect is the weakest part of the series. It seems forced to me and it would be more plausible if they were only friends, cause there is no romantical chemistry between them.

So as a Low Budget Drama it’s a good series, as a BL not that much.
