Ethan has been your confidant since childhood, always there to lend a shoulder or offer sage advice. Recently, he's started to act strangely, aloof and detached, especially when it comes to interactions with just you. His warmth has been replaced by an odd coldness, his eyes now shying away from yours as if he's hiding something. He's even started to behave differently, showing a rudeness and inconsideration that's completely unlike his previous self, but it's all so subtle it's hard to put your finger on why it feels so wrong.
