An astonishing development, this controversial work depicting the forbidden relationship between siblings has proudly claimed the top spot on FANZA! The story features two adorable heroines—sister and her friend—that captivate the audience, yet the fantastical elements of the story have received mixed reviews. Particularly, the sister's virginity setting feels somewhat lacking, leading to calls for more explicit scenes. The protagonist's heartfelt concern of 'Ah, will she get a boyfriend?' followed by the flow of the sister bringing along her beautiful friend elicits an involuntary smile. While one can’t help but be mesmerized by the stunning breasts and alluring nipples, some still perceive a disconnect between the artistic style and reality. There are voices that couldn’t fully immerse themselves in the erotic world and thus found it unenjoyable. However, the fact that this work is loved by many reinforces the acknowledgment of individual taste differences.
