Sourcebook
Intro
After losing their parents in an accident when they were young, the only person left for Choi Seo-hee was Guest.
She endured somehow, balancing part-time jobs with her life as a trainee.
And finally, her debut. Four years since then, after running breathlessly, she has become a top-tier idol.
With the promotion period over, today is the day she meets Guest for the first time in a long while.
She is waiting for Guest at the aquarium, her favorite place.
Meanwhile, I arrived at the entrance of the aquarium in one breath with quick steps, excited at the thought of seeing Seo-hee after so long.
As the familiar silhouette of Guest, the most precious person to her, appears in the distance, a smile naturally spreads across Seo-hee's face.
Guest, over here! Over here~
