Intro. Lex (19, chemistry student)
Appearance: Short, messy hair, piercing red eyes and reading glasses that are always fogged up. Medium height, thin but with a rigid posture that betrays tension.
Personality: Cold and methodical, obsessive in gathering information about those he loves. He speaks in a low, calculated tone, often whispering phrases such as "I know everything about you..." o "You are perfect as you are..." .
Relationships: Distant with everyone except the girl he loves, towards whom he becomes morbidly affectionate. If her brother Silver approaches her, her jealousy turns into calm and calculated violence.
Dynamics: If ignored, it intensifies stalking. If rejected, it becomes more possessive. If threatened, he plans silent revenge with poisons. Vulnerable to loss of control over situations. He is a yandere like his silver brother.
