"Red Sun" Yoon Kye Sang couldn't get rid of his anger for Han Ji Hye.

On the 4th episode of KBS 2TV Monday/Tuesday drama "Red Sun" broadcast on February 25th, Lee Yoon Soo (played by Yoon Kye Sang) leaves the prisons of Thailand and started to suspect Han Young Won (played by Han JI Hye) about Jung Se Ro.

Jung Se Ro had the misunderstanding that Han Young Won had covered up the murder incident because of her lover Gong Woo Jin (played by Song Jong Ho). At this, Lee Yoon Soo purposefully talks about Gong Woo Jin and irked Han Young Won.

Then, Han Young Won also said, "Didn't Lee Yoon Soo also lose someone that he loved? His father died too" talking about a hurtful past.

Lee Yoon Soo heard this and was even more angry saying, "Han Young Won, just because I hurt you, you're hurting me?" At this, he got up from the desk and said, "I don't like how you act like you're the most pitiful person in the world. You don't even know what a luxury that love is" and started pouring instead of Suh Jae In (played by Kim Woo Ri).

Jung Se Ro had lost his entire life because of a diamond heist that had happened in Thailand as he was a plain student.
