The series started great with huge potential for plot development but after 10 episodes I feel like most of the episodes are a filler episodes and there is no actual plot. It started strong but after 5-6 episode it lost momentum and we are going in circles...

Honestly there is no point in watching the whole episode, just skip from here to there and you'll understand what is going on( which shows that the story is easy to follow but boring af). The whole hiding personality is actually getting boring at this point .

The main couple was interesting the first few episodes but then they bored me so much omg... I actually like the development of the second couple more than the lead. Hm, honestly it's a easy forgetful drama ngl.

The whole story could've been better with 6-8 episodes, less filler scenes and more plot development.
The chemistry is great between the couples and side characters, but that's about it.
There is no point of re-watching this and waste your time again. You can live without this for sure.

~EDIT~
Last episode is airing in less than and half an hour, and my thoughts are still the same. The side couples were more interesting than the main one, due to the lack of communication, no character development and honestly not so great acting. The hidden personality "Kirin" was I guess the highlight of the drama...
This show could've been such a great hit in the BL world if the story development was better, if it had more substance to it.
Like I stated before, great start, weak finish. The only good thing about this show is the budget put into it. Other than that it's pretty boring,especially the main couple.
i do not care if you want to watch this, but take my advice and save your time. It's really not worth it.
