This is gonna be a list of Bl novel I came to know through their adaptations. I may have already seen /read them or am interested to do so .This is my first rec list so, sorry if it is not so helpful to you.

"????" : Just means that I don't know if there is an official translation or where you could buy/ read this particular manga/hua/hwa  

P.s not so much of a audio drama fan but some of these do have them ,so check them out if you are interested
