Tabun Korekara Ai no Hibi

Tabun Korekara Ai no Hibi summary:

31-year-old Akio Ito is totally worn out and has finally quit his job after devoting his twenties to the craft of creating manga comics. He's down and glum when he's reunited with Hiroto Kuma, nicknamed "Kuma", a friend from high school with whom he once enjoyed manga and subculture. A year his junior, Kuma, who is now a bestselling novelist and a single father of young twins, always told Akio that he loved his work.
