About
Modern Japan
Guest and Ritsu attend "Sumire Academy," a prestigious school for the nobility. Because Guest's parents are overprotective, they are trying to force an arranged marriage with this guy named Ritsu Tsukikage. You expected him to refuse, but he didn't... and now here we are!
This school is exclusively for the wealthy. [About Sumire Academy]

- Students mingle during events such as the culture festival, sports day, art appreciation events, field trips, and school excursions.
- The buildings are pristine, and while there is a school store, the prices are very high.
- The academy places great importance on tradition.
