Spoiler!
Tie was talking alone with Valentis. Even though her mind told her to be careful around him, he reminded her so much of her father that she kept trusting him more and more. She even ended up telling him things she normally would never tell anyone. Tie asked Valentis why he had cried earlier. Valentis explained that he had met someone he had missed for a long time, but that person was no longer the same person he remembered. Tie understood that feeling. She thought about her own father and how painful it was to lose people you love. She sadly said that happy times always end and that everyone eventually has to say goodbye to the people they care about. Valentis then brought up the knight Tie had been secretly searching for. Tie was shocked that he knew about it, but Valentis explained that information from all over the Holy Knight Order eventually reaches him. He said he thought Tie would be more interested in finding that knight than asking about his tears.
✕Tie admitted that she was searching for someone. She had been looking for a man she believed might be her father. The problem was that she did not know his real name. The name "Kim Young-su" might have been fake. However, she knew exactly what her father looked like. Valentis told her that the Holy Knight headquarters keeps an organizational chart containing the faces, names, ages, and information of all Holy Knights. Normally no one is allowed to see it, but he said he might let Tie look at it if she answered some of his questions honestly. Tie desperately wanted access to the chart because it could help her find her father. Valentis asked what relationship she had with the man she was searching for. Tie hesitated because revealing the truth could expose her secret that she was really only four years old. After thinking for a long time, she finally decided to trust him and admitted that the man she was looking for was her father. Tie then told Valentis everything. She explained that she was originally a normal four-year-old girl who lived with her father in Korea. Her father later died, and after strange events involving magic and another world, she ended up in Talochium and became the powerful Necromancer King. Valentis carefully listened and realized that Tie was not an adult pretending to be a child. She was genuinely a young child who had suddenly gained incredible magical power. He also understood that the members of her mercenary group had been protecting her and helping keep her secret safe. After hearing her story, Valentis agreed to let Tie see the organizational chart. Tie became incredibly happy and hugged him. However, she secretly used the magical bracelet called the Seal of Oblivion to erase the memories of everything she had just confessed to him.
I like to post spoilers for the stories I find interesting because I don't have much time to read novel due to busy schedule
