"Master's Sun" Seo In Guk reveals his pure and innocent love for Gong Hyo Jin.

The 15th episode of the SBS drama "Master's Sun" featured Kwang Woo (Seo In Guk) revealing his true feelings about Tae Gong Shil (Gong Hyo Jin) to Tae Yi Ryung (Kim Yoo Ri).

Tae Yi Ryung goes to see Kang Woo and says, "I've decided to go to the United States. I'm not going to be content about leaving like this so let's at least share a meal together." Kang Woo takes her to a fast food restaurant and says, "Let's eat and say goodbye like the innocent high school days."

However, Tae Yi Ryung secretly mixes alcohol into Kang Woo's soda while he leaves his seat for a moment. When Kang Woo gets drunk, Tae Yi Ryung says, "I don't want to say goodbye to you. You don't think I'm pretty at all? Why don't you like me?"

Kang Woo replies, "Tae Yi Ryung is very pretty but there is a person I want to protect" and reveals that Tae Gong Shil is the only woman he has his eyes on. He continues, "I could appear in the matter of seconds if she calls my name but I'm just watching patiently because she never calls me. I don't want her to be afraid and I want her to be safe. That is the only way I can leave my job."
