Short, slightly spiky black hair with only the back tied in a small ponytail. Hot-blooded, straightforward, and a hard worker who hates to lose. He never gives up in the face of adversity and values the bonds with his friends above all else. He is often reckless, which is both his greatest strength and his greatest weakness. He is best friends and rivals with Piao. He also competes with Meng Tian, Wang Ben, and Ying Zheng, though he has never beaten them in academics. He often fools around with Huan Yi.

Straight black hair that reaches his shoulders. His bangs are parted and reach below his chin. The side hair hangs naturally, partially covering his ears. He looks exactly like Ying Zheng. A gentle, intelligent, and highly responsible boy. In contrast to Xin, he is calm, polite, and excellent at being considerate of those around him. He is best friends and rivals with Xin.

Dark brown hair and prominent buck teeth. A friendly mood-maker who is deeply compassionate toward his friends. He has a cowardly side and can get cold feet in the face of danger. However, he never abandons his comrades and is the type of man who shows true courage when it counts. He is best friends with Xin and often hangs out with him. While they are rivals, their academic levels are about the same, which he finds a bit frustrating.

Dark brown, flicked-out medium bob. Her bangs are in clumps and slightly thinned. She has two cowlicks at the crown of her head. She sometimes tucks her left hair behind her ear. Occasionally wears a pale yellow headband. A bright, active girl with a quick wit. She can be foul-mouthed and short-tempered, but she treasures her friends from the bottom of her heart. She acts as the straight man to Xin's antics and is often dragged into his pace.

Black hair tied in a single ponytail at the back. Strands of hair hang down at the sides, and her bangs are heavy. A quiet, calm, and collected girl. She is not good at expressing her emotions, but she actually has deep affection for her friends and cherishes those she trusts. Contrary to her usual stoic attitude, she has a surprisingly airheaded side. Like He Liao Diao, she acts as a stopper for Xin and is often swung around by his energy.

Has a mole diagonally below his right eye. Chestnut-brown hair in a center-parted semi-long style. Several sections of his side hair are tied into thin braids. Aloof and free-spirited. He talks a lot of lighthearted nonsense, but he is actually extremely intelligent with flexible thinking and high judgment. Unlike his usual soft atmosphere, he has a very strong core. He often pokes fun at Xin and Wang Ben. He frequently tries to challenge Wang Ben to academic competitions (though he is ignored every time).

Black hair tied high in a single ponytail. He has no bangs, as his hair is all swept back into the ponytail. Thin strands of hair hang down at the sides. He wears two silver ring earrings in his left ear. Proud, serious, and a hard worker who refuses to compromise. He is strict with both himself and others. He shows respect to those whose abilities he recognizes and has a very strong sense of responsibility. He finds Meng Tian, who constantly challenges him to academic contests, to be a nuisance.

Straight black hair that reaches his shoulders. His bangs are parted and reach below his chin. The side hair hangs naturally, partially covering his ears. He looks exactly like Piao.

Black hair swept back, with the back hair tied high in a ponytail. He has some loose strands at the sides. Bold and free-spirited, he holds unorthodox views that are not bound by common sense or existing values. While he has a cold and cruel side, he is exceptionally skilled at reading human psychology. He trusts his own instincts and abilities, carving his own path without catering to anyone. He looks like he would be smart, but he isn't actually as bright as one might think. He often acts like an idiot with Xin. He doesn't like Li Mu and finds him annoying.

Fox-colored hair with a center part, reaching down to his cheeks. The back hair is tied high with a blue hair tie. A gentle, intellectual, and well-mannered person. He analyzes situations calmly and rationally, viewing things with a long-term perspective. He doesn't understand why Huan Yi dislikes him so much.
