Junjou Romantica: Takahashi Misaki is suddenly having some unexpected and odd problems. What started as a need for some college entrance exam tutoring has somehow led him to being romanced by a suave older man who also happens to be his big brother’s best friend. Confused by all of his brand new emotions, Misaki struggles to deal with his suddenly very odd life. And if that wasn’t enough, his suitor, Usami Akihiko, has plenty of issues of his own. A man-child who decorates his room in giant teddy bears and toys, Usami is a famous novelist who also writes steamy boys’ love novels on the side. When Misaki cracks open one of these books and reads sentences like “Usami licks every inch of Misaki’s hot body”…well, let’s just say that all hell breaks loose. Plus it doesn't help with Usami claiming he's in love with him.
Junjou Egoist: Kamijou Hiroki is a broken man, consumed by unrequited love for his childhood friend, Usami Akihiko (the writer from Junjou Romantica). Along comes Kusama Nowaki, whose name "Nowaki" means "typhoon", an orphan working his way through life since middle school. Like the typhoon he is named for, he whirls into Hiroki's life and heart, blowing all resistance away before him.
Junjou Terrorist: As fate would have it, Miyagi Yoh (whom Hiroki is working with as assistant professor) and Takatsuki Shinobu, a high school student, cross paths. Bits of pieces start to link together from the first two stories. That aside, Miyagi, who has a sad hidden past in himself involving a relationship with his teacher, is faced with Shinobu, who just says whatever is on his mind. The wheel of destiny is beginning to turn once again...
