Well, it's hentai that concentrates most of the waifu sperging shit, so... kind of expected.
I've seen the opposite happen - we're going back to the Mistress Ahri guy, I should really move my ass and open a thread on him. He hates Ahri hentai. He will yell and go nuclear on anybody who mentions it or says Ahri looks hot, and even took over some subreddits to make sure no Ahri hentai sub can be opened, quite the dedication. He's defending his waifu's purity so hard it's almost endearing, nevermind that she already had a boyfriend in her story.
She will truly love him forever when VR makes her real. I envy this man for his strength and devotion.
