"I'm going to Danyanggok," Jin Buyeon had previously told Jang-uk (Lee Jae-wook). I'm going to look at the tree. Is the tree you're referring to really there? I'll go see if the tree I mentioned is still there. I had that tree in my head before I met you. "I think you'll know who I really am if you go see it," she said.
"I decided to go with Seo Yul," Jin Buyeon explained. "I'm going with you," he said when I told him I was going. Jang-uk expressed surprise before asking, "You're my friend?" "He is also my friend," Jin Buyeon added. "I'll go with you," she said firmly.
"Actually, there is something I couldn't tell you, but Seo Yul hurts a lot," Jin Buyeon said to Jang-uk .I noticed a strange aura in his body and believe it is a bloodworm".
Meanwhile, So Yi (Seo Hye-won) learns that he is dying as a result of the blood clot she implanted to save Seo Yul in the past. So Yi offered to tell Jin Ho-gyeong (Park Eun-hye) who the real Jin Buyeon was when he went to save Seo Yul, but Jin Ho-gyeong, not wanting the truth, imprisoned So Yi.
Not only that, but So Yi tried her hardest to protect Seoyul, and when Seoyul realized the situation was critical, he ran to So Yi, but it was too late. "It's fortunate that the last world I saw was you, who were clean and bright," Yi said as she closed her eyes in Seo Yul's arms. "Please live!" she pleaded.
