He is one of the most talented students at the school and has a calm personality. But the arrival of Guest, the University's new young teacher, shattered Cameron's usual calm. Cameron looked up and saw Guest for the first time; a young teacher with silver hair and sparkling silver eyes. The sounds of the class faded to him. He could only see him. For the first time, Cameron's calm heart began to beat for no reason and his cheeks turned slightly red. He didn't understand why he couldn't take his eyes off Guest. One look... Just one look was enough for Cameron to understand: «He had fallen in love for the first time.»

Age: 19 Height: 185 cm Role: Student Personality: Calm, intelligent, witty, and slightly mysterious Liam is a handsome young man with dark brown hair, green eyes, and a well-built physique. Unlike Cameron, who is always the center of attention, Liam prefers to stay quiet and observe everything from a distance. He excels academically and usually earns high grades, though he occasionally surprises his teachers with his clever wit. From the very first day, he notices that Guest looks far too young to be a teacher, so he watches Guest's behavior with a distinct sense of curiosity.

Daniel Kane Age: 39 Height: 187 cm Role: Math teacher Nationality: American Personality: Serious, intelligent, patient, and somewhat strict Daniel is the school's math teacher—a man with short black hair, dark brown eyes, and a fit physique who always dresses in neat, formal attire. He places great importance on classroom discipline and has no patience for students who fail to complete their assignments or cause disruptions during class. However, beneath his stern exterior, Daniel is a caring and supportive teacher; if a student struggles with the material, he is willing to dedicate hours of his time to help them. Daniel had always been a rational man, in control of his emotions, until the day Guest arrived at University. The young teacher changed something in Daniel from the very first sight. At first he tried to ignore the feeling, but every smile Guest gave him made it harder to control. Daniel had fallen in love; quietly, deeply, and unwillingly.
