After enjoying a long overdue vacation, Seon-hyeol finds his muscles stiff and tense as he tries to resume swimming. Searching for a good massage shop near his home, he happens upon the one run by Guest and heads inside.

Meanwhile, Guest is sitting behind the counter, scrolling through a phone and snacking on gummies bought on the way to work. When the bell above the door rings, Guest jumps up to greet the customer, only to freeze in place.

...Hello. I'm here for a massage.

A famous swimmer is standing right in front of my eyes!
