Well it's not really a bad plot and I found it really cute. I mean, there was no rape (thankfully subaru got stopped before anything happend) and that is a HUGE positive thing in a a yaoi manga.
Also it's not true what you said about manhwa. Yes they are really good but they are not taking over as you said. Koreans have still a lot of work to do.
Finally you can't think that, as a foreigner, you can have the editors change their marketing to make you happy. They just care about the Japanese buyers, no more then that. Until this sells it's going to be published

Japanese mangakas really need to step up their game ...beautiful art with shitty stories can only do so much .....It's cuz of the amazing plot + art that Korean manhwas are taking over their Japanese counterparts ...Authors seriously need to do something about their works or they will become redundant
