Lee Dam and Shin Woo Yeo's Spend the Night Together

Lee Dam is back at Shin Woo Yeo's house. On the first night, the male gumiho requested if they could sleep in the living room, to which Lee Dam immediately agreed.

The two started to talk about their experiences and confessed the things that they liked about each other. While they were in the middle of a conversation, Lee Dam came closer to Shin Woo Yeo, which he found unexpected.

Shin Woo Yeo was trying to control himself not to kiss Lee Dam because he might transfer the marble to her, and it could lead her again to danger.

When Lee Dam fell asleep, the male gumiho couldn't help but to keep staring at her as if he was memorizing every detail of Lee Dam's face.

Choi Soo Kyung and Do Jae Jin Become Suspicious of Lee Dam Boyfriend

While on her way out of the library, Lee Dam met Shin Woo Yeo and talked about seeing each other again at home. They were surprised to see Choi Soo Kyung (Park Kyung Hye) and Do Jae Jin (Kim Do Wan) standing behind the wall and quietly sneaking up on them.

Lee Dam panicked because they seemed suspicious about her closeness to Shin Woo Yeo, who they knew as their professor.

To hide her true relationship with the male gumiho, Lee Dam volunteered to do their next project inside Shin Woo Yeo's house.

He was hesitant at first but ended up going with the flow. Meanwhile, when Do Jae Jin and Choi Soo Kyung were already in Shin Woo Yeo's house, they found some familiar things owned by their friend Lee Dam.

After their discussion, the group went to Shin Woo Yeo's dining hall to eat. Choi Soo Kyung then remembered Lee Dam's ex-boyfriend and started mocking him in front of the male gumiho.

On the other hand, the words of Choi Soo Kyung began to irritate the male gumiho and when he couldn't control his anger anymore, he shouted and made an alibi to excuse himself from the scenario. Lee Dam clarified that she and her ex-boyfriend got back together.
