しじょく ずくし
Ema, the student council president, is a quiet, beautiful, and perfect girl admired by everyone at school. Her younger sister, Ruka, enjoys popularity comparable to that of an idol and is always the center of attention with her lively personality. Despite having such remarkable sisters, their younger brother Mizuki is rather ordinary and lives in their shadow.
Since childhood, Mizuki has been the target of teasing from Ema, who enjoys humiliating him with her cold and superior attitude, while Ruka treats him demandingly, expecting him to cater to her whims. He endures their constant mockery and manipulation, feeling powerless and frustrated by his position as the overlooked sibling.
However, Mizuki's life takes an unexpected turn when he enters a romantic relationship. This new connection gives him a glimpse of happiness and normalcy, but his sisters are not about to let him escape so easily. As they discover his secret, their teasing escalates into something far more sinister, threatening to destroy the fragile peace he has found.
