Later Prince bring the two of them in the corridor and decided to listen about the plan. When Tin told him he just need to hide in Yeon Yihwa's room, Prince was mad because he knew Viole can easily stop his movement so it's impossible to catch him. But then Tin showed Boong Boong drink and told prince to drink that to increase his Shinsu Resistance. On a second thought, Prince canceled his intention to drink it since he was suspicious that he will be poisoned. Prince then decided to hand over the drink to Yihwa. After Yihwa drank that drink, she suddenly scream and felt there is something inside her body. When Tin and the green parasite entered Yihwa's room, Tin tells Sulsa that she is a good container because she was one of the 10 Great Families. Suddenly the green parasite jumped out from inside his cloak and forcibly enter Yihwa's body. Later, Prince was seen to run away to go back into his room and Yihwa was seen to lost her mind since she was controlled by the parasite which has infiltrated her body. The next time Tin appears is when Lurker returns into his room. It turns out Tin was the on who guarded Lurker's room. Tin then asked Lurker what is happening, but agitated Lurker immediately closed their door. Suddenly, Viole appears and Wangnan enters to hits Lurker.
