After having to deal with jealousy from his co-workers for working under
his father's name, prideful literary editor Ritsu Onodera is
determined to establish himself in the industry. To accomplish
this, he quits his job at his father's publishing company and
transfers to Marukawa Publishing. But instead of being placed
in their literary division, Ritsu finds himself working as the rookie
manga editor for the Emerald editing department, a team that operates
under extremely tight schedules in order to meet deadlines.
