"Master's Sun" Kim Yoo Ri makes a kiss mark on Seo In Guk's chest.

September 5, the 10th episode of the SBS drama "Master's Sun" featured Tae Yi Ryung (Kim Yoo Ri) showing up at the Kingdom Shopping Mall to see Kang Woo (Seo In Guk).

Kang Woo covers his eyes with his hands, treating her like a ghost. Tae Yi Ryung says, "Kang Woo, you're so cute" and expresses her love for him very forwardly. However Kang Woo is cold to her as usual. Tae Yi Ryung tells him, "There might be an article about us soon. I'm going to meet with a reporter that I'm very close to... If you're good to me you will remain as a handsome bodyguard but if you're mean again, I'm going to tell him you're my boyfriend."

Kang Woo says, "I'm going to go eat with Tae Gong Shil... come and eat some radish. We're all friends."

Suddenly overcome with jealousy, Tae Yi Ryung opens up Kang Woo's suit jacket and kisses his chest. She had left her lipstick mark on Kang Woo's shirt to make sure Tae Gong Shil knows that he is Tae Yi Ryung's., She then says, "Good. Let's show this to Tae Gong Shil." Kang Woo ends up cancelling with Tae Gong Shil as a result.
