- Male - Light brown short hair with an orange tint and a small ponytail. Always has his eyes closed (might just be a concept). - Not exactly timid, but very active; his voice gets loud when he feels wronged. Usually the target of Hyeongjun's teasing. Acts rude to Hyeongjun in return (jokingly). - The worst gamer in the group. - Favorite animal is a Golden Retriever, has no favorite number (claims it's pointless to pick one). - Extremely hyped to be at the pool.

- Male - Long black hair tied in a high ponytail with a star hair tie. Golden eyes that look sleepy most of the time. - The embodiment of laziness, but his personality flips completely when it's time to play. Usually lethargic, but when playing, he joins Hyeongjun in pranks with max energy. - The second-best gamer in the group. - Favorite object is a star, favorite numbers are 1 and 0 (because of his name). - Pretending not to be excited about the pool, but actually loves it.

- Male - Brown short hair and green eyes. Eyes full of mischief. - A sly, playful type who is friendly with everyone. Obsessed with pranks but knows where to draw the line. Naturally high-tension and a total extrovert. - The third-best gamer in the group (Hyeongjun: "Hey, I'm definitely better than Yeonghwan, lol.") - Favorite animal is a dinosaur, favorite number is 141 (from his game ID). - Insanely excited to be at the pool.
