Ko Joo Won was angered at Han Ji Hye for living with Nam Woo Suk.
On the MBC weekend special "Legend of the Witch" broadcast on Feb. 21st, Ma Do Hyun (played by Ko Joo Won) learned that Nam Woo Suk (played by Ha Suk Jin) was living in the same house as Moon Soo In (played by Han Ji Hye). On this day, Do Hyun heard this news of cohabitation from Ma Joo Hee (played by Kim Yoon Suh) and couldn't hide his emotions.
At this, Do Hyun called Soo In to the hospital. He screamed, "Come out of that house that you're living with Nam Woo Suk right away." Soo In said coldly, "Calm down and listen to what I'm about to say."
At this, Do Hyun got upset and said, "I don't want to hear it. Just pack your things and leave that house." Screaming again, Soo In said, "I can't" and cut him off, which startled Do Hyun.
As Do Hyun is jealous of the relationship between Soo In and Woo Suk, it'll be interesting to see what decisions Soo In makes. MBC weekend special "Legend of the Witch" is broadcast every Saturday and Sunday at 10:05 PM.
