Hi, here's the list of BL (Boys' Love) dramas and movies. Unfortunately, there are not many BL Korean dramas (almost none), but feel free to mention any BL dramas or films you can think of so I can add them to the list!
★ = the main plot is about gay romance side story= only the supporting character(s) are gay only hinted at = no explicit romance/sex, but hints at it in an obvious way
Jumong, one of the most popular Korean dramas of all time, had a canon gay couple in 2007--a secondary, peripheral but the two men were clearly spoken about as gay.
(i don't know anything about this but I planned to watch this.)
(there's also a 'kissing scene', but not sure if it's the main plot or side story).
I watched it and it was great. Its more mature as you have to pay attention and makes you think (not cute and fluffly at all). I would def recommend as its ont of the best BL movies I seen.
My Friend is Still Alive should be Bromance instead. The two male actor have no physical or sexual desire for each other. They are friends who are more than just friends. They love each other, but not because they are attracted to each other, but more rather because of the memories they had shared together.
