A mother who loves her son so intensely that she ultimately falls into a taboo mother-son relationship.

No longer treated as a woman by her husband, and seen by other men only as an old lady, the only one who still adored her was her "son." Gradually, the boundary between mother and son is crossed. What becomes of this sinful yet heartbreaking love will lead to an unimaginable conclusion!
