Ji-wook fell asleep while massaging Bong-hee's ankle. Looking at him, Bong-hee said she couldn't believe he had insomnia. She were happy to see his face alone but reminded her decision to give up on him and tried to control her feeling. 

Bong-hee loves to stay at Ji-wook's place but couldn't control herself falling into him every time she sees him. She began searching for a place to move. 

At that time, Yoo-jung, Ji-wook's ex and a prosecutor, grabs a group of people who tried to steal from a cafe. Bong-hee accidentally sees this scene and throw her kick to one of them. She fell and injured her ankle again. 

Yoo-jung helped Bong-hee to wear a cast at a hospital. They liked each other's personality and exchanged their name cards looking forward to meeting next time. 

Ji-wook found Bong-hee wearing a cast blamed himself for that. Bong-hee tried to explain the story but crushed to Ji-wook apologizing her again. She stopped talking about that and received his care. Ji-wook carefully cares for Bong Hee, and Bong Hee enjoys Ji Wook's service.

Ji-wook goes out for a drink to improve relations with colleagues at work. Bong-hee also came to same place with people from other firm. Bong-hee thinks it is a new job opportunity and does her best, but she gets angry because they were looking for just an entertainer for their clients. Ji-wook sees the scene and takes her out from them. 

Ji-wook told Bong-hee embarrassing herself that returned to work for him. She was confused, but Ji-wook fell asleep again in her arms after saying that now he would take a rest. 

Next morning, Ji-wook could only remember a fragment of last night. He asked Bong-hee if they slept last night. Bong-hee didn't give him a clear answer as a response to him who also didn't give a clear answer to her before and to the same question. 

She set a meeting schedule with the killer who disguised as an agent of scientific investigation team on the way out from their house. At the moment, Ji-wook saw Yoo-jung who was waiting for him in front of the door. 

Prince comforted Ga-Eun who was in sorrow. 

He felt bitterness that he couldn't reveal the truth before her. He promised to protect her even if he was not seen, giving her a pendant as a mark. 

He told her he would leave her for a while to keep her father's wish. Prince asked her to meet again three days later if she trusts her. 

At night, King told his biological mother that he permitted the prince's plan. Prince also revealed that he had a special heart to Ga-Eun. 

Ga-Eun found the letter from the crown prince that directed her father to investigate Yangsu-cheong. 

She went to the place with a sword shouting that she came to kill the prince and arrested. 

Prince taught Lee-sun in everything of the prince's life. He asked once again to confirm his determination to replace his life under a mask. Lee-sun replied to trust his heart. 

Prince heard Ga-Eun was once arrested and went out to see her. At that moment, the Chief commander brought Lee-sun to King under the crown prince's clothes. The entering ceremony was a day before than the date the prince knew. 

Prince went out to find Ga-Eun who was already released from jail but only found her letter and the pendant he gave. It said she couldn't be with him since his presence reminded her father. She though promised if she could hold her life longer she would like to see him again. 

Lee-sun went to the entering ritual of Pyunsoo instead of the prince. Gon recognized Lee-sun's face but didn't reveal for Hwa-gun. The loyal guard went together to attach Pyunsoo but failed. 

Meanwhile, Ga-Eun and the prince's mother seated at the place. She explained Ga-Eun that her father's death was not because of the prince but because of Pyunsoo. Ga-Eun couldn't accept that. 

At that moment, Dae Mok and his army broke into the palace. He came to punish the King who tried to deceive and kill him. 

Dae Mok said he could be the King since nobody knew the real face of the prince. The loyal guard arrived in King's room to protect the King. 

In prince's mother room, she was already poisoned and about to die. She told Ga-Eun that her real enemy was not the prince but Pyunsoo group. She urged her to find Chun-soo and died. 

Prince found Pyunsoo's army attacking the King and throw himself into the battle. 

Dae Mok figured he was the real prince and attacked him. The King, who was trying to protect his son, was killed first.
