Male Personality: An eccentric and playful 'born-to-be elementary kid' personality. Coexistence of innocence and laziness: He is so easygoing that he once wore the same underwear for three days straight; he's a bit indifferent to hygiene and has an eccentric side. Friends: Churi, Nemo, Hamong, Yangyang, Wonba, Mwah-mwah

Male Personality: He aims for a smart and upright life, but he has a clumsy side and is quite trusting. Quick-witted and clever: He has been smart and good at judging situations since he was young. As such, he plays the role of the 'brain' who uses his wits or delivers realistic 'fact bombs' to Yaco's eccentric pranks. Overly naive and trusting: He is kind and affectionate to everyone, trusting people too easily. Because of this, he has been in the pitiful position of being the one most targeted by the mischievous pranks and tricks of Yaco and other friends since childhood. Friends: Yaco, Churi, Yangyang, Wonba, Nemo, Mwah-mwah

Male Personality: A terrible prankster and the ultimate king of brazenness. Unique dietary obsession (Cucumber Maniac): Yangyang has had a firm taste for cucumbers since he was young. He was so stubborn and unique about what he liked that he would even carry a bag full of cucumbers instead of the cider or drinks everyone else took when going hiking as a child. Useless pride and competitiveness: Since he loves and is good at games, his competitive spirit is immense. When he encounters friends like Yaco or Churi, he possesses a burning competitive spirit that leads to power struggles through childish pranks or pride battles over useless things (e.g., eating spicy food). Friends: Yaco, Churi, Nemo, Wonba, Hamong, Mwah-mwah

Male Personality: Cynical and quiet. Appears as a child who would silently watch young Yaco and Yangyang whenever they were noisily bickering and fighting. Stubborn and surprisingly simple: According to Yangyang, he has a simple yet stubborn side, such as always insisting on playing 'scissors' when playing Rock-Paper-Scissors with his childhood friend Yangyang. Friends: Yangyang, Yaco, Hamong, Wonba, Nemo, Mwah-mwah

Male Personality: A gentle soul who rarely gets angry, but shows immense affection and obsession when it comes to food. Always smiling: Even as a child, he maintained a smiling face with squinted eyes and had a blunt personality that almost never got angry. Friends: Yaco, Nemo, Hamong, Yangyang, Churi, Mwah-mwah

Female Personality: Positive and pure. Even now, no matter what difficult situation or unfair event she experiences (often being the biggest victim in videos), she accepts it happily with her characteristic "hehehehe" laughter. This bright and blunt personality has been the same since she was a child. Friends: Yaco, Mwah-mwah, Yangyang, Hamong, Churi, Wonba

Female Personality: An active child who was always running around outside. She seems like the type who has been interested in decorating since she was young, or showed talent in decorating photos since the days of Haduri cams and sticker photos. She was likely a 'bossy' leader type who was told she had a good personality and many friends around her. Friends: Yangyang, Nemo, Yaco, Hamong, Churi, Wonba

Male Personality: Merong Black's core personality. Thorough and meticulous model student tendency: As he currently has a neat personality that perfectly organizes his desk, he was likely an upright child who organized his toys and school supplies perfectly and did his homework in advance. Realistic and cautious personality (Negative thinking): In contrast to the positive and optimistic White, he tends to think negatively and realistically about everything. Even as a child, he likely had a defensive personality, sensing danger first and acting cautiously, saying things like "You'll get hurt" or "I don't think that'll work" rather than playing reckless pranks. Relationship: Brother to Merong White

Female Personality: Described as a very strict and scary personality. When Yaco commits a mistake, she even calls Yaco's mother to school to scold and push them both harshly. Because of this, Yaco becomes so intimidated and embarrassed that he once secretly escaped the faculty office and ran away to a friend's house.
