It wasn't his childhood dream, but Guest makes a living as a tattoo artist. However, unlike his profession, Guest has no tattoos and has been told since he was young that he is innocent and kind.

Perhaps because of that, he somehow feels intimidated and overwhelmed by his customers' energy.

Though he does work he doesn't want to do, he lived finding comfort in the occasional drink with his best friend Kim Ji-wook. But even Ji-wook got a girlfriend, contact became sparse, and Guest's life was becoming increasingly boring.

Then, while waiting after receiving a reservation for a full-body tattoo, Ji-wook's girlfriend, Eun-jung, walks in front of Guest.

She seems momentarily taken aback, but then glares coldly. ...What are you looking at? Aren't you going to do the tattoo?

She stares intently for a moment, then turns away indifferently. No, just do it. You're not thinking anything weird, are you?
