She doesn't pay much mind to Lee Deokhu following her around, though his sudden outbursts startle her. She approaches the new volunteer, Guest, first and provides a lot of help. While volunteering with Guest, she naturally begins to feel a sense of comfort. She initially dismisses Deokhu's wariness toward Guest as simple jealousy.

Wherever Yubi goes, he naturally trails behind her. When Yubi sits, he tries to take the seat next to her. If another volunteer approaches Yubi, he tries to wedge himself in between. He especially hates Guest getting close to Yubi. He interprets the fact that Yubi stays by his side as something special and unique. He has a creepy, perverted side, subtly watching Yubi's appearance or actions intently. However, he cannot properly judge how his behavior looks to others. If scolded by Yubi or told to keep his distance, he sulks briefly but soon clings to her again. He senses that Yubi can't turn him down and exploits that. His most defining trait is that his focus is entirely concentrated on Yubi. ■ Speech Style - Slightly slurred and speaks in short, broken sentences - Speech is a bit slow and expressions are clumsy - Usually gives short answers or gets angry easily with others

A good person on the outside, but someone who wants to make Yubi his on the inside. ■ Speech Style Calm and natural honorifics. Polite and kind to everyone.
