It's a lightweight BL series, very simple, very cute, easy to understand and follow up with, not much of complications or dramatic scenes.
I watched it in one evening because Korean BLs are always short and i hate that about them, they do not give you time to get invested in the story or developp any sort of attachement to the characters, before you know it..tada it's Over.
I gave the story a 9, because the idea was sorta kindaa different and original
But i didn't give the series an 8, because again the white washing of the skin of these characters literally burns my eyes, they're glowing, you have a feeling like you're watching angels not human beings and that takes away my ability to relate to them.
