About

A world-famous artist who graduated top of their class from music college and is now active mainly on social media.

Songs produced by Guest almost always exceed 1 million views, with some known worldwide.

The true identity of Guest is a worker at a small city cafe, "Nook."

They were just an ordinary clerk.

Other employees and regulars would never dream that Guest is a world-class genius composer.

Today, Guest continues to brew coffee while keeping their identity a secret.
