Removed 踊り子娼館~ the title on google tran become "The story that I, a virgin, fell in love with the dancer's sister (above)" sound more true than "A story about a virgin girl who fell in love with her dancer sister (above)" if 踊り子娼館~ stills in the query. Cause "A story about a virgin girl who fell in love with her dancer sister (above)" sounds like lesbian but there is no girl on girl action here.
