Japanese Name: 彼女の妹と秘密のステイホーム～内気娘が背徳寝取り！
Summary: ❤️‍❤️‍❤️‍ Sayoko Amanshu and Aritomo Harase have started living together in preparation for marriage. At that time, Sayoko’s family home was to be renovated, and her parents decided to move to a rented house closer to their workplace. However, Sayoko’s younger sister Emiru’s school is far away, so she ends up living with Aritomo’s house near the school for a limited time. Emiru is bad at socializing and is a little out of place. At first, she didn’t greet Aritomo or talk to him, but as time went on, she started to open up to him and her moody mood disappeared. And then one day. When Emiru and I were working side by side, she pretended to be a coincidence and Emiru kept clinging to Aritomo and entangled her legs with hers. Then, she looked at Aritomo, awkwardly but somehow seductively.
