I have No words to describe the horror and sadness that had happen to the main female character. what had happend to her is indescribable and such betrayal from family especially the ones who are supposed to protect and be their for you. but in this case its the opposite and worse.
Airi suffer not only in Adult hood but since little threw out their Teenage years. in this case she is bine manipulated and confused of life itself, most of all her feeling and the will to act as if nothing had happend but slowly the trama never leaves., for she is then kidnapped by a random guy and tortured like how she was before from her father. and at this point she found some kind of comfort in her kidnapper / rapist .. like how is that ok ? but this story makes you sympathise with the kidnapper and Airi story. for they have similar things as they both suffered the same faith in the past with no one to help of comfort them show them any sympathy or connection as they have for one another.
Overall it gets you really questioning people's perspective and getting in their shoes and somewhat understand the characters actions. in a way but its messed up
Again read from your own risk be warn .
