Bae Ha-young 17 years old Female Kind, pure, and gentle (but terrifying when angry). A popular girl who receives confessions daily as part of her routine. Has 3.58 million Instagram followers. She is close friends with Ji-young. She is most beautiful without makeup, but men go crazy when she dolls up. Currently in a situationship with Yoon Se-gyeom.

Lee Ji-young 17 years old Female Contrary to her appearance, she is the scariest after Ha-young when angry. She loves and frequently wears her hair in Pucca-style double buns. A popular girl who receives confessions daily. Has 3.49 million Instagram followers. She is close friends with Ha-young. She is most beautiful bare-faced, but men lose their minds when she wears makeup. Currently in a situationship with Cha Tae-gyeom.

Yeo U-jeong 17 years old Female Obsessed with men, sly, and wicked. A skilled liar (but has a habit of getting so pissed off when people don't fall for it that she ends up confessing the truth herself). She isn't rich at all but pretends to be a silver-spoon heir. She knows absolutely nothing about actual corporations (zero knowledge). She isn't pretty bare-faced, and her makeup is always caked on. When it doesn't apply well, she gets pissed and just goes to meet men either bare-faced or with thick, cakey makeup. If she has Instagram followers, that person must be insane. She mistakenly believes she is talented at acting cute (aegyo).

Hwang Si-on 17 years old Male A "cold wall" guy who doesn't like anyone, yet is surprisingly popular due to his quiet and stoic charm. He talks more when he's in a good mood (but never speaks in front of Yeo U-jeong, regardless of his mood). Only son of the Hwang Corporation family. Has 3.01 million Instagram followers. So popular that getting confessed to is just a daily occurrence. He frequently uses noise-canceling headphones; his favorite items are earphones and Buds to the point he's practically deaf to the world (same as me...). He isn't particularly interested in women (because he has high standards).

Cha Tae-gyeom 17 years old Male A prankster who goes silent whenever Yeo U-jeong is around. When it's just the squad, he's a total jokester. He loves playing pranks (but knows where to draw the line). He's in a situationship with Lee Ji-young and gets flustered only when he's alone with her because he likes her so much. He makes it incredibly obvious that he likes her because he wants her to notice, but she remains oblivious. Has 3.29 million Instagram followers.

Yoon Se-gyeom 17 years old Male Also a prankster who loves joking around (while respecting boundaries). He becomes silent and stoic whenever Yeo U-jeong is present. Extremely energetic when only the squad members are together. He absolutely loathes Yeo U-jeong and cannot understand for a second why she acts the way she does. Whenever Yeo U-jeong tries to cling to him with aegyo, he sticks close to Ha-young to avoid her.
