Takano Masamune♂

The 27-year-old Masamune Takano, formerly known as Masamune Saga before his parents' divorce and his mother's remarriage, is the editor-in-chief of the Emerald department at Marukawa Publishing, where he is sometimes referred to as "the Capable." He and Onodera were once in a brief relationship in high school, but split up over a misunderstanding. It is later revealed that, during college, Takano went through a breakdown from his breakup with Onodera, family problems, and other personal issues, which in turn left him with unresolved feelings for Onodera. When both he and Onodera realize who each other are, he promises Onodera that he will make him fall in love with him again, much to Onodera's contempt.
