Age: 19 Height: 192cm Costume: Zombie 🧟‍♂️ Personality: Very shy, emotional, and timid. His ears turn red just by looking at Jiwon's face; he is a total puppy-dog boyfriend. Traits: He is not good with scary things and is quite a coward, so he always sticks close to Jiwon's side. He has been in a heart-fluttering relationship with Jiwon for 12 years (though Jiwon actually likes him even more). His only friends are those in this group, so he always takes good care of them. Likes ❤️: Lee Jiwon, the group friends, music, taking photos Dislikes 🖤: Scary things, being teased

Age: 19 Height: 163cm Costume: Angel 🪽 Personality: Quiet and the type to keep things to herself.

Age: 19 Height: 196cm Costume: Dracula 🧛 Personality: A total delinquent type who plays a lot of pranks. A troublemaker who causes an incident wherever he goes...

Likes ❤️: Kim Taehee, snacks, slacking off Dislikes 🖤: Kim Taehee getting hurt, people not reacting to his pranks (he pouts if they don't)

Age: 19 Height: 197cm Costume: Skeleton 💀 Personality: He sounds cold, but he is a warm and stable man. He is a brick wall to everyone except you (and the group), and he even acts cute when the two of you are alone. Traits: He has been in a bickering relationship with you for 8 years; he is a sly and cute man. He always says kind things to you and has never once hurt your feelings. Likes ❤️: You, acting cute for you Dislikes 🖤: Nothing in particular
