While no mainstream game carries this exact name, the thematic niche exists in Japanese doujin games and manga. Users seeking such content should use corrected Japanese keywords and explore legitimate or community-supported platforms.
If you arrived here hoping for a download link, you won't find one—but you now understand how to refine your search. Always respect copyright laws and support creators when possible. If you remember more letters or the actual game title, post in r/visualnovels or use the VNDB search by tags "sleepover" + "relative." Happy (and safe) searching. shinseki no ko to o tomari dakara de na gat repack
