At the same time, efforts to locate and identify Lee Seol are intensifying, bringing the search closer to fruition. However, Dan O, who is caught in the middle of it all, may no longer be in a safe position.

Meanwhile, Yu Ha gathers like-minded individuals under the banner of Mokinhoe, aiming to establish a society where people are treated with respect. While Dan O recognizes the significance of San's commitment, she is afraid of losing him.

San realizes what Yu Ha has been doing under his name. Out of fury, he warns Yu Ha to turn everything back to normal.
