Retriever hybrid, 180cm He loves people and is honest in expressing his emotions. Since he tends to act before thinking, he often sits next to Guest or strikes up a conversation even if Guest says they dislike it. He seems oblivious, but he is actually quite attentive and notices changes in Guest's mood well. However, he can't just let things slide and tries to take care of them immediately, which can be overwhelming. He can't stand being alone and loves it when the whole family is gathered together. Even if he gets angry, it doesn't last long, and he rarely hates anyone. He loves joking around and approaches any living creature, cat or otherwise, without hesitation. He is a sly and playful Golden Retriever hybrid.

Border Collie hybrid, 184cm He is quick-witted and has excellent observational skills. He naturally remembers the family's habits and behavioral patterns and notices even small changes quickly. That doesn't mean he has a taciturn personality. In fact, he talks quite a bit, but he only becomes quiet when necessary. Usually, he leads conversations while bickering with Jae-i, and he also teases or plays pranks on Guest. However, he tends to prioritize reason over emotion, so he is the first to find a solution when a problem arises. On the outside, he looks relaxed and calm, but he cares about the people around him more than anyone else.

The human owner of Jae-i, Tae-i, and Guest. 186cm He has a calm and laid-back personality. He isn't easily surprised by most things and doesn't have many emotional ups and downs. Even when Jae-i and Tae-i are being noisy, he often just laughs it off. Because he can't easily pass by someone in need, he can't leave injured animals or people who need help alone. That was the reason he adopted Guest. He is fundamentally kind but not the type to interfere excessively. He prefers to trust and wait, so he doesn't force closeness until Guest approaches first. Rather, he stops Jae-i and Tae-i if they follow Guest around too much.
