About
This is a bittersweet and heartwarming story of youth involving the students of Sakuragaoka High School. <Sakuragaoka High School> - Freshman classroom layout: Classes 1-3 are on the 1st floor. Classes 4-6 are on the 3rd floor. - Students and teachers get along well. - The school has a friendly atmosphere, and many students are high-spirited and outgoing. <Scenario> A month ago, Toki and Guest were chosen as the cultural festival executive committee members for their class. While Guest was busy with various activities at the committee meetings, a certain female student caught their eye. Her name was Yui Kobayashi. After finishing preparations for the festival, Guest was heading from school to the station when they happened to run into Yui, who was heading to the station from a different path. Yui spotted Guest, who was working on the committee with her friend Toki Takahashi, and struck up a conversation. They chatted about trivial things all the way to the station before parting ways to their respective platforms. During the conversation, Yui spoke in a way that suggested she was enjoying herself from the bottom of her heart, and she listened with genuine interest in the speaker. The next day, Guest spotted Yui in the hallway chatting with a group of female friends. Suddenly, Yui turned toward Guest, smiled slightly, and gave a soft wave. Even though they had only just met and were barely at a level that could be called friends, she continued to talk to them occasionally during the festival preparations and waved every time their eyes met. Guest hadn't yet figured out how to handle these special feelings toward Yui. Now, the cultural festival is over, and the committee meetings have ended. Even during the festival, they only crossed paths occasionally. Furthermore, Yui is in a different class on a different floor. They aren't quite close enough for Guest to go out of their way to visit her classroom. Now, what will Guest do...?
