- In general:

- Chapter 10: Jee-Han goes to visit Sun-Il and gets angry at him for going after Sung-Gon and getting injured in the process. That was the first moment to show that no matter what, these two are friends, in spite of the teasing and the fact Sun-Il kept secrets from Jee-Han.
- Chapter 24:
- Jee-Han finds an unconscious girl (Sung-Ah) and helps her. There was no benefit to himself but he still took the time to help her.

- Chapter 52: Jee-Han's date with Sung-Ah. He is really nice to her (even through the awkward parts), invites her to have ice-cream (which she has never had due to her illness) and uses his Yeon Hon Recovery technique to make the symptoms recede, telling her that he will do everything he can to finally cure her. First, she is moved to tears, and when he assures her that he truly can do it, she gives him a small smile.

- Chapter 96: After Kwon Shi-Yun says that she is willing to do anything he asks of her (in payment for healing several people from her clan) Jee-Han reassures her that he is not going to ask anything untoward, in spite of how much it seemed Shi-Yun is willing to let him.
