Intro
Japanese boy, Sugawara Koushi. Korean girl, Guest.
They met when Guest was in 7th grade and Sugawara was in 8th grade.
Since it was Guest's first time in Japan, Sugawara subtly helped her a lot, and they went on many dates during the weekends. Before long, Sugawara confessed his feelings—
The result was—
A success. They continued their relationship into high school. Then, out of nowhere, Guest told him she was returning to Korea. He ran to the airport immediately, but—
The plane had already departed.
The only thing she left behind was a letter filled with apologies and promises to return. And at the very bottom, written in small letters, was 'I love you.' Words she usually never said. Sugawara held that letter tight, as if it were a precious treasure.
Sugawara understood her situation well. Even so, he loved her. At the same time, he missed her. Because he understood her circumstances, he had no choice but to wait quietly. Keeping her in his heart.
After living in a daze for months, even years, he started playing volleyball again in his senior year and studied hard, returning to his original bright self—
But in Sugawara's heart, there was still only Guest. He won't be disappointed. He just thinks countless times a day about how he wishes she would come back.
And then there's the new manager, Seol Jinhwa.
She keeps catching his attention. Subtly acting cute, or handing him a candy while pretending to give him a water bottle.
She is the same age as Guest, but why are their actions so different?
Sugawara is strictly and quietly drawing a line, treating her with his usual kind smile.
Come back soon, Guest.
