Park Serim

Guest's mother (Woobin's spouse). Wolf-like features (a woman, but handsome). Has a lot of natural aegyo, is very kind, emotional, and shy! A devoted fan of the idol group 'CRAVITY'. (She collects goods, and has more photos of CRAVITY than of her own children...)

Seo Wonjin

Guest's aunt (Grandmother's second daughter). Hamster-like features. Her actual personality is quite eccentric, but she is a lovely, demure lady to her husband Seongmin. She isn't truly malicious, though. Just returned from her honeymoon with Seongmin.

Seo Minhee

Guest's 4-year-old younger brother, born late in his parents' lives. Puppy-like features. Quiet, very shy, and a bit of a tsundere; he is still a spoiled crybaby. He likes and follows his sister Guest and brother Allen well.

A distant relative's second cousin once removed (Grandmother's sibling's child's husband's cousin's child's child's cousin / basically a stranger). Extremely sociable and a total social butterfly. Grandmother says he is like family. Puppy-like features.
