Synopsis: Thor is an illegitimate child. One day, his mother took him to his father's house, hoping that his father would take in the homeless mother and son. But his father was not at home that day, and his father's first room opened. They were treated inhumanely in the first room. In the end, the mother died with a grudge, while Thor was led into the house by his dead father and began to be bullied.
The only one who is kind to Thor is the neighbor's daughter Mingta, but the warmth Mingta can bring to Thor is limited after all. In an accident, Thor fell into the sea. His stepmother thought he was dead, but in fact, he was lucky to be saved by a kind person. After more than ten years of dazzling, Thor returned to his stepmother anonymously with only one purpose, and that was revenge.
