This is the second title in Lass Pixy’s low-price single-heroine Little Sick Girls series. This time, Akito learned about the secret of his class’ loner and problem child Ruchie by chance. This caused her to suddenly become attached to him, becoming diagnosed as an ‘attachment type’ Little Sick Girl. Ruchie doesn’t open to others after her parents’ early deaths, and she became an idol after being cheered up by an idol during her most painful times. After becoming an LSG, she just wants to have sex with Akito all the time.
