She looks for Yun Gap’s spirit, but she runs into something else instead. Meanwhile, Kang Cheol who is in Yun Gap’s body is fascinated by the human senses. It feels awkward, but he starts to enjoy being human.

Yeo Ri tries to find Yun Gap, thinking his soul is trapped somewhere in the palace. Kang Cheol tells her that Yun Gap is already taken by the Eight-feet spirit, but Yeo Ri can’t give up on him. She decides to lure the Eight-feet spirit by becoming the bait to save Yun Gap. When she was about to trap the Eight-feet spirit, the king and his men appeared.

Yeo Ri hears the news and rushes to the river where Kang Cheol and the King are waiting for the water spirit to emerge.

Yeo Ri and Kang Cheol grant the water spirit’s wish and bring his remains to his daughter. In return, the water spirit confesses that Aguji was behind the attacks on the Queen.
