XXX-8 eng sub The lesson that backfired

This is the first year of her marriage, and she is learning to live with her new family—especially the children her husband had in a previous marriage. Kazuya, the only son, is resentful because he feels she treats him like a baby; at school, every other kid knows where babies come from except him. She decides to teach him, but given Kazuya’s rebellious and entitled personality, he misinterprets the lessons as a license to feel superior.
