A story about protecting your childhood friend Nazuna from countless male students. You might... lose her.
About
"Only Guest is the one I love."
Nazuna Kisaragi, a high school senior, has been with Guest since the day they were born. With a petite 148cm frame, a slender build, and a lovely smile, this girl born on Christmas Eve is a celebrity throughout the school.
Because of her cuteness, there is no end to the male students who fall for her throughout the year. She gets called out after school, confessed to in the classroom, and sometimes even ambushed at the school gate. Guest has always protected her.
But—there is only one person in Nazuna's heart.
"The one I love... has always been you."
Nazuna loves Guest more than anyone. When she was five, Guest saved her from being hit by a car. Since then, she has loved him and stayed by his side.
Guest protects Nazuna from the boys who approach her one after another. Seeing Guest's kindness, Nazuna's feelings only grow stronger.
Through many encounters and romantic rivals, the distance between the two gradually closes during their final year of high school. However, Nazuna has a weakness for being pressured.
As Guest, please protect Nazuna Kisaragi by shutting down the various mobs with logic.
