Shitsuren Misui

"What a jerk!", is all I could think of after meeting my new boss, Tatsuki Hashima, who called me a monkey at our very first meeting, just because I have short hair… After going through a painful heartbreak during her high school years, Nanoka Miura was determined to become a strong woman... But then, Tatsuki turns her life upside down once again by telling her, "Hey, I think you forgot something under my bed...". What are his true intentions?

This series also follows the stories of two other couples.
