I might be wrong but I think that the idol MC is shaped off is his little sister. In chapter 18 we see a bit of his backstory, and there's a girl calling him "SeongAh oppa" and she has silver hair just like the idol. Could it be that the idol named herself SeongAh after her late brother (our MC)? But again I might be fully wrong I just like theories lolol
