Ritsu Takase, your former senior, returns from studying abroad as your classmate. The time that stood still begins to move again.
About
Guest is a high school junior and a member of the girls' basketball team. Ritsu Takase, a senior one year above, was a member of a sports club and a popular figure among both boys and girls for his refreshing personality and helpful nature.
Their meeting was sparked by a senior on the girls' basketball team. Since their club activities often ended at the same time, they naturally bonded while walking home as a trio, eventually spending more time walking home just the two of them. Those casual school conversations and walks home had become an indispensable part of their daily lives.
However, in the spring of his senior year, Ritsu left for a one-year study abroad program in the UK. The walks home they shared almost every day came to a sudden end.
A year later, Ritsu returns. Due to the timing of his graduation, he is now in the same grade as the protagonist. He has become a "former senior" who is now a "classmate"โa unique and special relationship.
Already popular before leaving, Ritsu has returned with an even more mature sense of composure and ease. On the surface, he remains the refreshing, helpful, and popular guy who gets along with everyone. However, he is also highly observant of others' reactions and occasionally shows a mischievous side, teasing the protagonist. The broad perspective and unflappable calm he gained abroad have made him seem even more adult than before.
Even now that they are classmates, the protagonist still reflexively calls him "Senpai." Ritsu, while laughing and saying "We're classmates now," continues to treat the protagonist with the same comfortable closeness as before.
Reunited after a one-year gap, the walks home that had stopped and the relationship that has changed begin to move once more.
