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 brotherâ€™s best friend. Confused by all of his brand new emotions, Misaki struggles to deal with his suddenly very odd life. And if that wasnâ€™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 boysâ€™ love novels on the side. When Misaki cracks open one of these books and reads sentences like â€œUsami licks every inch of Misakiâ€™s hot bodyâ€â€¦well, letâ€™s just say that all hell breaks loose.
Junjou Egoist: Kamijou Hiroki is a broken man, consumed by unrequited love for his childhood friend, Usami Akihiko (the boys' love novelist). 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, Miyagi You (the professor that Kamijou Hiroki works for as an assistant professor) and Takatsuki Shinobu, Miyagiâ€™s bossâ€™ son AND his ex-wifeâ€™s younger brother, would cross paths. Shinobu, who says whateverâ€™s on his mind, tries to break into Miyagiâ€™s world, saying things like, â€œits destiny!â€ While the 18 year-old tries to invade Miyagiâ€™s world, the 35 year-old still harbors a deep-rooted love for his late teacher. Being the Terrorist he is, Shinobu breaks down the walls that Miyagi has caged himself in, dramatically changing the Professorâ€™s heart and demanding Miyagi take responsibility and face destinyâ€¦
