Shy college student Shizuka moonlights as 'Shiro' online, anonymously broadcasting erotic content to his followers. Of all his followers, 'Kuro' is by far his favorite: a dark-haired hottie who's always first to leave a comment. One night, while fantasizing about Kuro, a fateful misdial leads Shizuka to accidentally masturbate to an audience of one.

'Kuro' then reveals himself to be Kurosaki, Shizuka's classmate and Mr. Popular! Thinking he's being blackmailed, Shizuka agrees to be Kurosaki's project partner, but Kurosaki has an agenda of his own in mind...

Now that Kurosaki knows Shiro's identity, just how far will Shizuka go to make sure his secret account stays secret...?
