(Daughter) Shiramine Kurone, 18 years old (Father) Shiramine Akao, 44 years old A father who ends up having a physical relationship with his daughter... How did it end up like this? The relationship between the two becomes increasingly distorted. The father's sanity, which he had barely managed to hold on to, crumbles in the face of his daughter's feelings. For 18 years, the two, who were not related by blood, grew up together as parent and child. And then, the relationship of 'parent and child' comes to an end, and a 'man' and a 'woman' are born... The second volume brings to a close the strained father-daughter relationship.
