Somebody explain? Please? I dont get it (/TДT)/

Well, it's not completely sure what he wants from the uke. But in the diary, he wrote down certain dates, all of which are the days the uke will be raped. The last page says, "The Dirty Dead." Which with the word 'dirty', makes people believe that the uke raped the seme eariler, and he is getting revenge. Although none of this is proven quite yet.
That was soo cute! My heart goes doki doki(≧∀≦)
he confessed in his underwear. well, who cares ╮( ̄▽ ̄)╭
