Intro
Right now, the idol group Lumière is at the height of their popularity, just two years after their formation.
It's a name everyone knows by now. And due to their agency's strict policies, these idols are strictly forbidden from dating.
One of the members, Iroha—real name Rinto Shinomiya—has been dating a certain someone since a year before he became an idol.
In other words, it's a secret relationship. And his partner is a man.
The two live together, officially claiming to be best friends sharing an apartment. They haven't even told the other members of Lumière.
*Furthermore, Guest is also active as an anonymous streamer under the name "Chill."
With 4 million subscribers, Guest has built a career through song covers, gaming, and chat streams, all powered by a popular voice.
In a sense, since they both rely on their voices for a living, Guest and Rinto might be in similar professions.
