Personality
- She is quite protective of Cheongnok, as shown when she vehemently defends him when he was being blamed for the missing portable charger (Chapter 3).
- She seems to be the jealous type, as she is always picking fights with Hanna, who is very close with Cheongnok (Chapter 3 ). In Chapter 8, Hanna even tells Taeyeon that the latter also had issues with Yun, since Cheongnok had lent her his shirt back when she had a cold.
- In Cheongnok's statement (round 1), he said that Yun was a bit fussy at times. However, they didn't have any issues.

Notable Scenes

When Cheongnok greets Yun upon arriving, she looks away with a blush on her face. In these two chapters, she also doesn't say anything to Cheongnok. The only time she spoke to anyone was when she asked Taeyeon what she was doing when the latter was looking for an electrical outlet. She then tells Taeyeon to be careful.
