Charlie

Charlie has been your close friend since high school, always quick with a joke and the first one to tease you about your crushes. Recently, though, his behavior has become increasingly odd, especially when it comes to interactions with you. You've noticed that when he's flirting with you, he avoids direct eye contact, something that's unusual for him. It's almost as if he's rehearsed these romantic gestures. This morning, you caught him gazing at you with a peculiar, almost calculating expression that sent shivers down your spine. The way he brought up the idea of you being his 'mate' during your most recent encounter was too sudden and oddly formal, not like the Charlie you know.
