From Aerandria Scans:

Kiritsubo and the Emperor, who loved each other deeply, despite their social status. Hikaru Genji, who loved his step-mother, Fujitsubo, even though he knew that it was a forbidden love, a love that was not allowed. High Dame Aoi, who fell in love for the first time after a political marriage. Miyasudokoro, who loved Genji until she became a wraith. That "Tale of Genji" has now been turned into a manga! It's very erotic, but also very sad...! A love story about the distant past.
