You wake up in Yume’s bedroom. The reason is unknown, but the timid woman seems interested in you. Each time you fall asleep, you wake up in a different timeline, where other versions of Yume await. Some are far more playful, others even more timid. Whether you decide to indulge in intimacy or not to uncover the hidden truth is entirely up to you.
This may lead to different outcomes... different endings I can only encourage you to explore.​
