But before getting into the details, here is a quick recap of episode 16. The sequel began on a happy note by featuring the reunion between the conman and his biological mother. Things took a turn for the worst after Mo Yoo-ran informed her son that the person he is looking for is his step-mother Kang Seo-hee.

Since the male protagonist knows that serial killer Ma Dae-young and his family's next target could be his father Heo Gil-joong, he seeks his detective friend's help to trace them. They head to the property agent's house with a fake identity and start searching for evidence against his step-brother and his mother.

However, Lee Min ho's character becomes emotional seeing his father locked up in a dark room and starts confronting him for choosing the wrong person as his mistress. However, the loud and furious conversation between the father and the son alerts the housekeeper. She informs Heo Chi-hyun about it, who was with Shim Cheong.

While returning back home, the silver-tailed mermaid meets the serial killer and he chases her. Towards the end of the episode, she sets a trap for him and tries to erase his memories. Will she succeed in erasing his memory?
