In "Mask" Joo JI Hoon checked that Soo Ae was living and knew about her whereabouts.
On the episode of SBS Wednesday/Thursday drama "Mask" (script Choi Ho Chul, director Boo Sung Chul) broadcast on July 29th, Choi Min Woo (played by Joo Ji Hoon) was framed for the murders that Byun Ji Sook had committed.
On this day, Choi Min Woo went through the fire and went into the mansion. With that, he walked in and hugged Byun Ji Sook. Afterwards, Choi Min Woo passed out. When he awoke, Byun Ji Sook was not next to him. Instead, there were pieces of clothing with blood next to him.
Min Suk Hoon (played by Yeon Jung Hoon) put the murder crime onto Choi Min Woo instead of Byun Ji Sook. With that, he was at the risk of being imprisoned. After being dragged off, he heard the voice of man saying, "Byun Ji Sook you stay there."
Choi Min Woo verified that Byun Ji Sook was alive. To find her, the police officers scurried on the streets and ran away. After tracking the GPS location, Choi Min Woo found Byun Ji Sook. Choi Min Woo said, "I'm sorry to be late" and Byun Ji Sook and he shared a hug.
