Emma Verde came to Japan from Switzerland at 16 y/o to fulfill her dream of singing and dancing on a stage. Now that she's 18 and a third-year, she's also a nationwide famous solo idol. She fell in love with Kyousuke after joining the Koikatsu club, but her status of rising star in the idol world prevents her from having a boyfriend. She also knows that Kyousuke is in love with Yokoi Yuzuha, his girlfriend. She occasionally meets up with Kyousuke (with Yuzuha's approval) to have sex and create intimate memories of her first love, knowing that she will have to let it go very soon.
