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.

(above) in title should be written as "former" or "1st part"

when there's (上), there will be (中) and (下) part...
