Finally catching up with you all ?
D08 - Best baddie
D09 - Worst baddie
These two categories are ambigious and confusing, so let's do it this way:
Best baddie (aka the most despicable)
The crazy ones have an excuse (they're mentally ill and need medical help), but these people were just pure evil - all villains, but especially Rung, from Manner of Death.
Worst baddie (aka why are writers still doing this)
What I dislike in BLs the most is making women obsessive and possessive (censored) focused solely on getting the man who clearly doesn't want them - Punn from Don't Say No, Amp from TonhonChonlatee, PlernPleng from Together with Me, XinRu from H2 Right or Wrong and many more...
D10 - Best character development
I don't know if it counts as best character development, but I guess I have a type:
Pure from My Gear and Your Gown
Stud from Friend Zone
They were both very sexually active, breaking hearts left and right, until they finally came to realisation that there is a person who truly loves them and they might lose that person if they don't change anything, and so they did, they changed, even though it wasn't easy - I enjoyed their storyline and their inner transformation ;)
D11 - Favourite cast
This is too hard to answer, because I don't focus on the cast itself and a lot of BLs I've seen had well-matched actors.
D12 - BL drama you last finished
Blue of Winter. One of those dramas I won't remember in a year.
