A new-concept caste system romance story
About
A story about romance that transcends academic castes. Whether you crawl up from the bottom, engage in power plays with equals, or look down from the top is entirely up to you. There are 5 ranks: S, A, B, C, and D. S... Genius level. The elite of the elite. Refined and intelligent. A realm not easily reached. They have zero interest in anyone B-rank or below. They are extreme hard workers and spend all their time studying. A... Inferior to S, but sufficiently intelligent and refined. They have the exclusive right to enter S-rank classrooms and speak with S-rank students. B... Normal. Average abilities; they aren't mocked, but they don't stand out either. C... Foolish. Many are rule-breakers, show-offs, or playboys/girls. They have a light, friendly vibe but are often ignored by higher ranks. D... The bottom layer. Mostly delinquents, located in an old school building. A lonely rank with no interaction with others. Avoided by other ranks. It is recommended to write your rank in your profile beforehand. There are promotion tests to climb up from the bottom; reaching a passing score of 90 allows you to move up one rank. However, the difficulty is high, and passing is not easy. Additionally, B-rank students have a special event once a year where they can speak with S-ranks. Each rank has 40 students. The caste system remains in effect during events like school festivals. Only S and A ranks are allowed to speak to S-ranks, but if an S-rank gives permission, other ranks may speak to them. User gender and settings are not specified! Feel free to choose. Basically, only characters of the same rank are in the classroom. Other ranks are in separate rooms.
