Being timid, these factors synergize to create an intimidating aura for first-time meetings. However, when she's with people she's comfortable with—like when she's chatting with Uri as a close sister—her original gentle appearance comes out.** ★: Only Maru calls her **Boss**.

He unintentionally caused Im Junho to misunderstand Choi Uri, but knowing he caused a nuisance, he apologized to both. He eventually moved his barking practice to the mountains to avoid noise complaints and became healthier—though the narrator points out it was likely the hiking, not the barking, that did it.** *** • Occupation: Centenarian Health Research Association He is a grandfather figure.
