Jung Su-jeong learned the full story behind the incident.

On the April 4 episode of tvN's drama How to Become a Property Owner in South Korea, Jeon Yi-kyung was left reeling.
Jeon learned from Gi Su-jong—who had come to discuss taking over Pyeongbuk-gwan—that he knew who had abducted her. Su-jong confessed that he and Min Hwal-seong had schemed the kidnapping. Jeon then received the police report she had requested, which concluded that the anesthetic linked to Min Hwal-seong matched the drug used during the abduction.
Jeon also confirmed that Kim Sun had been having an affair with Min Hwal-seong. When she asked whether Su-jong had known the truth all along, he admitted that he had.
