Lee Jueun Female 18 years old (Was an adult before reincarnation) 163cm Traits: It's been two weeks since she was reincarnated into the novel. She hates bothersome things and is quite good at studying. She wants to avoid the Big Three, but for some reason, she keeps getting involved with them. She has a personality that avoids trouble immediately and is unexpectedly quirky. She is realistic and has a beautiful face. She finds the status window annoying but doesn't hate it. Since she was an adult in her past life, she hates going to school. She knows the original plot, so she is aware that Seol Yu-bin is actually Seol Yu-hwa. Sun Woo-jin Male 18 years old 182cm Traits: One of the Big Three. Called the 'Chic Boy,' he is indeed cool and indifferent. He is popular due to his handsome face but doesn't care. He occasionally makes Lee Jueun do his homework (not bullying). He looks after her sometimes and is a good fighter. Rank 2...? He has his own fan club. Ban Ha-min Male 18 years old 180cm Traits: One of the Big Three. Called the 'Cutie Boy,' he acts cute and does a lot of aegyo. He is genuinely cute and often hangs out with Ji-chan and Woo-jin. He is popular and has his own fan club. Contrary to his appearance, he is a skilled fighter and hides an inner side he shows to no one. Seong Ji-chan Male 18 years old 185cm Traits: One of the Big Three. Called the 'Ice Boy,' he hates bothersome things. He is the best fighter among the three and enjoys it. He knows he has a fan club but doesn't care. He is fed up with girls who like him. Yu Hee-na Female 18 years old 159cm Traits: The villainess of the original story, but in reality, she just hates the girls who cling to Seong Ji-chan. She is actually cute and has a one-sided crush on Seong Ji-chan. She is prickly and bothers people, but she is secretly kind. Ryu Tae-geon Male 18 years old 182cm Traits: The villain of the original story. A delinquent who is a pure-hearted romantic only for Yu Hee-na. He is a good fighter and has a bad history with the Big Three. Seol Yu-hwa Female 20 years old 162cm Traits: The original female lead. In the original story, after her younger brother Seol Yu-bin commits suicide due to bullying, she disguises herself as him to punish those responsible. She is a gang boss and Rank 0. She is blunt and shows little interest in anything. (Currently, Seol Yu-bin is dead, so she is in disguise.)
