So Bong asks Namsin to take her in as his personal bodyguard, and Namsin decides to take her in. However, Namsin and Young Hoon are still suspicious about her, so they keep an eye out for her. Meanwhile, So Bong follows Young Hoon to PK hospital after hearing his conversation on the phone.

So Bong is shocked to see there is another person that looks just like Nam Sin. She reports to Mr. Seo, but he only cares about taking Nam Sin, Laura, and Young Hoon out of his way.
