Koi Jigoku de Matsu

A hellish cohabitation life that begins after death. "I wanted to see you again. Even if I went to hell." Saginomiya Raku, a con artist who died in an accident, unexpectedly reunites with his high school classmate, Gotokuji Manabu, in hell. Manabu was once a bullied kid, and worked hard because he admired Raku. However, for Raku, Manabu was the person who caused his life to spiral downwards. And now, even after death, Manabu has been waiting for Raku in hell, saying he desperately wanted to see him again. As punishment for his misdeeds in life, Raku is forced to live together with Manabu in a hellish apartment. Raku wants to escape this life of punishment as soon as possible, but Manabu, who is happy to see him again, seems to be enjoying himself and declares that he will not let him think of this as punishment.
