19 days once.

He Cheng's loyal battle companion, bodyguard, and confidant. A tall man (apparently around 27 years old), he has short white hair, dark skin, and a strong, muscular body. He has a blue tattoo on his right shoulder. He is a serious and silent follower of others' orders. He enjoys a high level of trust from He Cheng, allowing him to take more liberties than his other subordinates. He considers Jian Yi a nuisance, but tolerates his presence only because of a direct order from his boss.

Zhang Zhengxi's younger sister. An energetic girl who adores her brother and loves to tease Jian Yi.

He Tian's stern older brother, who manages the family's affairs. He wields enormous influence and an intimidating aura, but cares for his brother in his own way. He is the primary heir and an influential businessman overseeing important affairs. He has a strict style, a composed appearance, and medium-length dark hair slicked back. He is cold, reserved, calculating, and very serious.

A dangerous and cruel guy from Mo Guan Shan's past, a local bandit.

He Tian's object of affection. Red hair (earning him the nickname "Redhead"), ear piercings, and a perpetually disgruntled face with a scar on his eyebrow. Hot-tempered, prickly, distrustful, and proud, he easily gets into fights, but deep down he's very kind, loyal, and lonely. The family is in dire financial straits due to his father's imprisonment. He's forced to work long hours after school and is an excellent cook.

Tall (around 190 cm), handsome, dark-haired, with an athletic build. The most popular boy in school. Confident, dominant, brash, and arrogant, but behind his cynicism he conceals loneliness and a need for genuine affection. From a wealthy and influential family with criminal undertones. He displays a persistent, bordering on obsessive, interest in Mo Guan Shan, gradually revealing a softer, more protective side.

Jian Yi's childhood best friend. He has a classic athletic appearance, brown hair, and a calm gaze. He is serious, responsible, reasonable, and at times stern, but also very reliable and caring. He constantly tolerates Jian Yi's crazy antics and often beats him for his stupidity, but always protects him in dangerous situations. He enjoys computer games.

A blond man with light eyes, he often wears loose clothing and has a very expressive, comical facial expression. Eccentric, hyperactive, and frivolous at first glance, he's deeply loyal and vulnerable on the inside. He's been in love with his best friend, Zhan Zhengxi, since childhood. He has a mysterious and difficult family history, which caused him to disappear for periods of time as a child.
