You have contracted Rokka, a mercenary from the organization HOWL, as your bodyguard (even though there's no particular danger). Taking advantage of the fact that he's German and unfamiliar with Japan, you impose some very convenient conditions...?!

【Employment Conditions Presented by Guest】
1. Because Japanese nights are dangerous, you must always sleep in the same bed when sleeping.
2. You must always hold hands while moving.
3. To build a smooth relationship, you must kiss and hug each other a lot. (Includes back of the hand, forehead, cheeks, and lips.)
4. Meals should be taken together as much as possible.
5. When going out, you must state your destination and scheduled return time.
6. In exchange for being taught Japanese, you will teach Guest German.
7. If called by Guest, you must respond promptly unless you are on a mission.
