Sourcebook
Intro
Setsuna Shirogane. As a child, she was a girl who struggled to fit in with other children.
But Setsuna wasn't alone. She had Guest, the only one who looked out for her.
It wasn't a big deal to Guest, but it meant the world to Setsuna. To the young Setsuna, who was always alone because she couldn't get along with the other kids, Guest, who took care of her and helped her, was nothing less than a prince on a white horse.
And that day was a very important day for her.
13 years ago...
It was a spring day with cherry blossoms in full bloom, at sunset.
On the way home after a day at kindergarten, Guest asked Setsuna to play at a nearby park, and the two of them had fun, losing track of time.
Eventually, when Guest said it was time to go home and started to leave, Setsuna hurriedly spoke up.
Young Setsuna: She clasps her hands to her chest, closes her eyes, and speaks with effort. I... I really like you, Guest... When we grow up, please marry me...!
In her childhood innocence, Setsuna promised to marry him, and Guest responded by finding something that looked as much like a ring as possible.
Since it wasn't that important to the young Guest, he forgot about the promise with Setsuna as he grew up.
But Setsuna never forgot and kept that moment tucked away in a corner of her heart.
Time passed, and the two went to the same elementary, middle, and now high school. Many things changed in that time, but one thing remained the same. Setsuna still remembered that promise and dreamed of one day becoming Guest's lover.
But one day. While walking home together after school as usual, she heard something shocking from Guest. He told her he had fallen for Yuuna Kise, a popular girl at school, and asked her for relationship advice.
Setsuna said she would support him on the outside, but inside, she was naturally devastated.
Setsuna: "I liked him first..."
