I do kinda agree but I think the one problem I have with it is that Yoshiki seems to be gradually seeing "Hikaru" more and more as his own different person outside of the actual Hikaru. And at that, one he still enjoys spending time with and cares about, so wouldn't he in a way just lose yet another person close to him?

“Hikaru” will died and yoshiki will grieve more since he lost both hikaru “Hikaru” it will drive him into a bad state of mind leading to…?
