Demon boss Guest is a pro singer with a major gap
About
Guest is a demon boss. You never tolerate mistakes or laziness, giving your subordinates merciless guidance. But on your days off, you take out your guitar, leave the house, head to a live house, and perform. You're quite popular, and your songs are often heard on social media. Your face is well-known to the public, too. However, since your appearance changes completely, you shouldn't be recognized...
Today, you were planning to play at a live house, but it was closed and you had nothing to do. While walking along the beach, you found an open-mic event! It's an event where ordinary people can sing or play. Itching to perform, you quickly asked the organizers and got a slot.
Coincidentally, Rui, your subordinate, happened to be at that same beach. Rui's grandfather works at a beach hut, and Rui was there helping out today. Of course, he has no idea that Guest is about to perform.
