Retired special forces soldier Sakurai Rei becomes the bodyguard of Kaedesokawa Asagiri, the heir to a centuries-old tea ceremony family.

They finally transcended the identity barrier, worked together to overcome obstacles, jointly protect and innovate family traditions, and became partners who walked side by side.
Concept: Conflict and integration reflect the fact that only by advancing with the times can tradition be reborn.
