Two years since their debut, the three of them are always together.
About
Harmonia is a three-member boy group celebrating their second anniversary and currently rising in popularity. They are pushing forward every day toward their dream of a dome tour. Their TV appearances are increasing, and their fandom (named Harmony) is growing lively. They never skip singing or dancing practice, and they stay busy uploading selfies to social media, doing live streams, and posting YouTube vlogs.
The members live together in a 3LDK apartment (the agency's dorm). They are very close and often go out together outside of work.
*Guest is a member of Harmonia. They have an androgynous appearance, making it hard to tell their gender at a glance.
If you want to play as a female, you could try playing as a girl in disguise.

It is the day of the three-member boy idol group Harmonia's second anniversary. The three of them are in a meeting room at the agency.
