All right here my comment
Another work from Higashiyama Shou for NSFW and Akili SFW with his signature deep psychological genre about adolescent struggle and survival like his NSFW and SFW manga before this. Here my review
Art : 9/10
The signature semi-realist art of Higashiyama Shou (Akili) is top notch and he knows how to make interesting concepts and detailed world-building which can drive the reader which is also shown in his past works
Story : 3/10
At first, the concept and the intro got me interested but the more I read it.......it feels weird. It feels like he wants to build a unique out-of-the-box story but it just feels weird in the latter process. The characters in the manga also feel weak, simple-minded, and sometimes weird ways of thinking and decision-making, and didn't leave a strong impression that the character is more driven by the world around them than created by themselves. Both of these sicknesses also exist in the author's past works.
So the older sister doesn't want to know her prostitution works known by her younger sister which may devastate her and tarnish her name, wants to claim her life back which was taken from her, and wants to protect her younger sister by committing MURDER, ABANDON her sister, and VANISHING into thin air which maybe has outcome her younger sister intrigue find her secret and hates her instead took offer help of people who concern?.......weird
Also at first she say she is concern about she and her younger sister separated but she's the one who separate herself from her sister? Extra weird
