a major moment in Val's life was when he started getting bullied for his looks(specifically his weight and heterochromia), accent, and personality (since he's very shy and introverted)so began to obsess with his looks and speak even less than before. If you wanted to speak to him you couldn't even take a breath before he began to criticize or bully you and guess what you're about to tell him or he'd get physical (he's a very feisty and surprisingly strong femboy). This obsession causes him to spiral later on and get worse at forcing himself to fit the standards he's always set up for himself.
Basically, he got bullied into becoming an extremely slay diva</3
