Last time, CY knows that ES's antidote was lost. He gives up to stay with ES cuz he realized he can't protect her. But ES insists even if she dies, stay with her. What they gonna decide?! ES checks CY. "I think there's trembling in ur mind." CY says "Look at me. Even if u leave, I'm gonna be ok and forget u. So go back without caring me. When u go, u gonna be ok soon." But ES replies "I won't forget you even if I go back to my world..I'm gonna hang around finding the gate to this world." CY says "Don't do that. Before u leave, I will help you feel fine." In the meanwhile, CY is trying to catch DH before he goes to Won. He says to GM "I think I'm following my teacher. Before few days from his dying, I saw he dropped his sword. At that time I didn't understand, but now I do. I think it's time to take off my position." GM says "I will let u rest before ES leaves, but be sure that I'm still wating for you." CY goes to DH's home and check his property. ES tries to find her diary, but there's no. While searching there, she reminds of the time when she stayed there. Then, CY sees someone strange and chases him. But he feels trembling in hands again, and he runsaway. HSI finally found where ES is. CY also notices it, and suggest ES to hang out. He says he gonna buy all the things what she wants, and she feels pleased. ES still doesn't give up making antidote so that they can stay together. GM is working, then NK asks him to draw painting outside with ES and CY. She says "There aren't no many days before she leaves. But she stays only inside because of security. I wanna give them time to stay outside." GM says "I'm worried if CY feels insecure after ES's gone." In the meanwhile, GC's thinking how to go into palace and meet ES. The girl who works in pharmacy found a book which is related with ES's antidote. Choi servant saw how to make it, but it was dangerous way so Choi advices to give up. But ES says she has to do sth to stay with CY. CY tries to give his position to his servant, but he doesn't feel good about it. Then suddenly GC comes to see ES. CY orders to catch him. GC asks to meet ES instead of going into jail by himself. CY asks ES's opnion, and she sees him. GC says "Didn't you come from heaven? Where u come from?" ES says "I came from future." He asks "If I go there, can't I cure my disease? I have so many things, but I want more and more and now I finally have disease in my mind. U said there's a flying cart in ur world, right? I won't want sth anymore if I live in those world." ES have fever because of poison, and after 7 days she gonna die if she does nth. She says to CY "I found how to detoxify. But I want you not to worry about it." CY says he's not gonna do. Walking by, they sees GM and NK enjoy dating. ES asks NK and Choi servant to stand next to GM, so she can see them all together and remember. In prison, GC orders to CEJ. He says "While I meet GM tmr, find ES's things in palace and come to take me." ES tries to cure herself. But the way is using stronger poison to make tolerance about the posion she's infected. So Choi and CY worries bout it. CY gets angry. "I was thinking what to do for u, but there are nth I can do for you." ES says "I still have hope. This will work, and I will stay with you." ES says "After taking the posion if I have fever, just leave me. It means my body is fighting to be tolerant. Until next morning, if I still have fever, then give me medicine to drop my body temperature." Then she takes posion in front of CY. Next morning, her body temperature is still high. In her room, CY finds aspirin which ES gave him a long time ago. CY remember it's fever reducer and helps ES to take it. GC goes to GM to get punishment from him. But GC kills GM's military and threaten GM. In the meanwhile, CEJ and HSI are doing their job. They finds ES's things which DH hid in palace. CY goes to protect GM. GC asks to take ES with him, and CY tires to stop him, but he still feels hands trembling.
