"My Heart Shines" Jang Sin-yeong seduces Bae Soo-bin but calls Jeong Eun-woo

 Soon-jin (Jang Sin-yeong) was hostile towards Woon-tak (Bae Soo-bin) on the eighteenth episode of the SBS weekend drama"My Heart Shines".

Woon-tak ordered someone to tell him what Soon-jin did and where she went. Assistant Park (Do Gi-seok) told Woon-tak that she went to the market before she went home. She didn't meet anyone. Woon-tak told Park to keep a tail on her.

Soon-jin was putting on a button on Woon-tak's shirt. Woon-tak asked her casually, "Did you go somewhere today?". Soon-jin said she was at her aunt's shop but people had taken everything and it was about to be auctioned off.

Woon-tak apologized for being inconsiderate and said he would do something to make sure that doesn't happen. Soon-jin got up to kiss him. Woon-tak said, "That's sleazy. What are you doing? Were you being hostile to me because I didn't take care of your business?"

Soon-jin took his hand but he seemed hesitant so she hugged him. He took her to the bedroom and said, "This is all your fault".

Meanwhile, Soon-jin was being tapped by her husband so she decided to use Eun-bi's (Ha Jae-sook) phone. She called Gwan-mo (Jeong Eun-woo) and asked about Soon-jeong (Nam Bo-ra).
