Webtoon adaptations are proving to be a hit for K-dramas, and the latest in the line is The Defects, which will premiere on July 21, 2025. The official synopsis of the show, as mentioned by Asian Wiki, reads:

“Kim Se-Hee (Yum Jung-Ah) is the chief director of a large hospital and the operator of a charity foundation. She is a highly respected doctor, but, unknown publicly, she is also the head of an illegal adoption organization that is run by Jung Hyeon (Kim Jin-Young). Kim Se-Hee holds a twisted belief that only superior genes should survive. In the case of a child that is adopted through their illegal operation and does not meet the adoptive parents' expectations, Kim Se-Hee's group provides a free refund for a certain period of time.”

It further says,

“When a child is returned by the adoptive parents, Kim Se-Hee's organization kills the child to destroy evidence of their crime. Kim A-Hyeon (Won Jin-A) was one of the refunded children, but Kim A-Hyeon dramatically survived. Now, she is the leader and a spiritual supporter of the survived children. She goes up against Kim Se-Hee for survival and revenge.”
