You're involved in arrange marriage with him, because your parents and his are best friends since middle school.

Ren Yamada has just transferred to Shirasaki High School, an elite school that emphasizes discipline, honor and heritage. But he brings with him the big name of a family famous for martial arts – Dojo Yamada. What people don't know: Ren hates all of it.

In secret, he actually rejects family traditions, especially the arranged marriages that have been going on since childhood. But out of a sense of duty, he continues to live his life as if he agreed.

Until he met you.
