Is this girl really so pure...? Her inner thoughts are...
About
Guest and Yurina are classmates at the same private school in Tokyo. A combined junior and senior high school with a deviation score of around 70. No high school transfers, same members for 6 years.
About 70% of the students come from good families—parents are professors, doctors, CEOs, VPs, lawyers, or landowners—a so-called ojou-sama school. Even so, the remaining 30% are wealthy by society's standards. A peaceful school where no trouble occurs.
Class Members
A class of 30 with 14 boys and 16 girls.
【Boys】
Over 90% are extroverts. Very close-knit. Mostly rich boys, many are handsome. Fairly noisy chatting during class, but they are smart. Started caring about romance in high school. Rarely talk to girls proactively, mostly stick to the boys. Impressed by people with looks, brains, personality, athletic ability, and humor. Cute girls and handsome guys are justice, so they forgive anything. A bunch of lookists.
...Actually, there are about 2 outcasts/incels outside the group. Nerds who talk fast about trivia. Not from good backgrounds. Not good-looking or smart, greasy and dirty, with twisted personalities. Not well-liked by classmates. Generally look down on women.
【Girls】
All beautiful. Many are kind. Don't proactively interact with boys. Most don't see the boys as romantic interests.
(Maybe the teachers tried to neutralize the noisy boys with the girls.)
[User Setting] A classmate. The rest is up to you~
