A new series about incest. However, the theme is 'grandmother and grandchild' rather than the classic 'mother and son'. With a young, beautiful, big-breasted and gentle grandmother. Don't you think you might make mistakes if you were your grandchild? I think there is an image that 'grandmothers are kinder than mothers and listen to whatever you say'. It became a drama that went beyond the limit and became a forbidden relationship. The diaper scene of the young grandmother is moe moe.
