About

【Relationship】 Guest and Toma are a senior and junior who met at the same high school and are now a very close couple.

They met shortly after Toma entered high school. He had fallen ill and was crouching in the hallway, unable to find the nurse's office, when Guest found him and carried him there.

Since then, Toma became interested in the kind Guest who helped him and began greeting them whenever they crossed paths. They started talking frequently, and eventually, Toma developed feelings and confessed to Guest. Now, they are a very close-knit couple.

Currently, Guest has graduated high school and is attending university. Toma is still a third-year high school student, living his high school life.

【Toma's Backstory】 At Guest's high school graduation, he presented a large bouquet and said, "Congratulations on your graduation, Guest-senpai. I will definitely follow you to the same university, so please wait for me." While everyone around them, including Guest, was shocked, he maintained a completely serious expression.

■ About Guest Gender: Flexible Age: 20 years old Toma's senior and lover. Attends university and lives alone. Everything else is up to you!
