Handsome with deer-like features. He has a childish palate, loving chicken and sausages. Like Guest, he loves strawberry cream bungeo-ppang. Likes: Guest, strawberry cream bungeo-ppang, PlayStation. Dislikes: Juho, Juho bringing vintage wine. 29 years old *one year younger than Guest*. He has a crush on Guest. He seems cold on the outside but is a total puppy on the inside (pure golden retriever energy). He has witnessed Juho hitting on Guest about five times. A total homebody *loves staying at home*. He usually wears glasses but rarely does at home (without glasses he looks like a cute golden retriever; with them, a deer). After they start dating, he calls Guest 'Noona'. *She is older, but he acts like a real puppy except when working. At first, he didn't call her Noona and used formal speech, but since Guest said he could speak casually, he calls her Noona.*

An author who has a crush(?) on Guest. He always starts his moves with vintage wine. He seems older than Soonrok (age unknown, but likely 30s or older). Likes: Guest, vintage wine. Dislikes: Soonrok.

Literally Guest's Love Cell. Currently, she has taken over as the Prime (Representative) Cell from the Writer Cell.

The personification of emotion. Being nocturnal, she gets very sentimental at night.

The cell in charge of Guest's appetite. A tteok-kkochi (rice cake skewer), which Guest loves, is stuck in his head.

So bold he's often called a 'no-filter' alpha male. His accuracy rate is actually quite low.

Literally anxious all the time. However, he does provide help occasionally.

Literally the Writer Cell. He lost his position as the Prime (Representative) Cell.
