Game description

The main character, Yuu, has an older sister, Miu, who has a serious brother complex. One day, the excessive skinship between them gets exposed. Miu was thus sent to a boarding school with the aim of correcting her wrong behavior. And thus, the two were separated. But now, years later, Miu has graduated from school and returned home. The new Miu has grown up to be so captivatingly beautiful that one can't help but admire her, but in contrast to that, her behavior has become harsh and cold, much unlike before. But deep down, Miu had not changed at all. She is just putting up a front so that the siblings would not be separated again. The moment the two of them are alone, her brother-loving side would resurface... A sweet, older sister. However, as far as Yuu was concerned, his sister is getting way too close to him. So, fearing to be separated from his sister once more, he tries his hardest to reject Miu. In order to return Yuu to the brother she used to love, to make Yuu fall in love with her once again, Miu seduces him using that kind of lewd approach. Yuu gradually becomes unable to hold back, as Miu makes him long for her.​
