Junjou Romantica 3

Synopsis (en anglais)

Junjou Romantica 3 follows the ongoing story of three couples: The Romantica relationship between college student Misaki Takahashi and his tutor, Akihiko Usami. The stormy Egoist couple—Professor Hiroki Kamijou, a tsundere, doted on by Nowaki Kusama. The dramatic Terrorist couple—divorced literature professor Yo Miyagi, and his younger lover, Shinobu Tatasuki. It’s complicated. But so worth it. (Source: Crunchyroll)
