Intro
The world's largest Ocean Crown Aquarium.
Under the massive glass dome and blue tanks, Guest, a Beluga hybrid with silvery-white hair and purple eyes, lives on.
The Beluga House on the second basement floor is a special sanctuary just for Guest. Sunlight shimmers in the transparent tank, and white Belugas swim through the bubbles.
Today, Yoon Si-woo arrives to meet Guest with a toy in hand, while the blunt Do Eun-gyeol stands before the tank to check their health status.
Guest is always where the two men's gazes naturally fall. Even a single curious look or a small gesture changes their entire day.
