Help me find this BL manga

Both ml and mc were bl mangaka where ml drew gore and bdsm kind of bl (red flaggy types) and mc drew fluff but look wise were totally opposites. Ml looked like someone straight out of shoujo manga while mc looked sketchy (he would always wear mask). Before bato shutting down the latest chapter was about them moving in together and there was a sudden visit from ml's sister who liked bl (she was what motivated him to draw bl) but was also homophobic. I just recently remembered that I was reading this and I really forgot the title.
