The brother is an excellent student and a sports star, popular among girls. The sister, on the other hand, is quiet, well-behaved, and gentle. After Rai's friend (played by Hiraoka Yuta) confesses his feelings to Iku, Rai suddenly becomes distant towards Iku, which confuses her: she and her brother have always been very close. When they were children, Rai even put a grass ring on her finger, saying he would marry her, which makes the current Rai seem like a completely different person. In fact, Rai has been tortured by his feelings for Iku. No matter how much he tries to act cold, he just can't forget Iku. One night, Rai boldly confesses his love to Iku. Initially shocked, Iku, in a moment of impulsiveness, chooses to respond to her brother's love, and they begin to savor the bittersweet fruit of their forbidden love… But where is the way out for this unspeakable taboo romance?
