Ballad ni Shitekure

The Tachibana and Akiyoshi families have always been close, especially after Akiyoshi Hiromu's father passed away and the Tachibanas took care of him and his younger brother. After graduating from university, Hiromu accepts an invitation to work at the Tachibana family's frozen food company, eventually becoming the secretary to Yuusuke Tachibana, a womanizer known for his irresponsibility at work.

When Yuusuke's father falls ill with cancer, the company is left in Yuusuke's hands. In exchange for good behavior at work, the young boss makes a shocking proposition to Hiromu: move in with him and share his bed.
