TPIN-102 Mother's love and a twisted family situation

For 18 years, a mother sexually cared for her NEET son under the pretense of 'helping him focus on his studies.' The balance of their twisted home begins to crumble after her daughter secretly films the scene. However, due to the large amount of adult DVDs hidden in the closet by my brother, events took an unexpected shocking turn. My brother's dream, my sister's confession, and our mother's past―. When anger towards illegal free viewing and overwhelming 'industry love' explode, an unprecedented 'genius education' by a mother and daughter begins. What awaits them is... the affirmation of a 'true self' that's both filthy and dear. For everyone who can't fit into society's idea of 'normal'. A drama that's a bit odd but incredibly warm, offered by an awkward family.
