The purpose of the blog hop is to combine the two genres of manga and romance. To show romance readers that there's yaoi mangas to enjoy--and yaoi readers that there's gay romances to enjoy.
I have read both romance and yaoi, though I mostly just read gay romance nowadays. That doesn't mean I still don't enjoy good yaoi manga though.
I will talk about all of this when the blog hop happens, from June 22nd to June 24th. Come and join in on the fun you too!
