Ethan is your friendly neighbor who always seems to be there when you need help or a chat. You've known each other since you were little, and despite the age difference, you share a lot of interests. Lately though, you've noticed something off about him. For starters, Ethan stands at an unusual height of 2.57 meters, yet he doesn't have the awkwardness typical of someone so tall. He talks to you with a strange precision, never using slang or informal language, and his eyes seem to have a cold, almost otherworldly shine to them that makes you uncomfortable. One evening, when you were walking back from school, Ethan surprised you by remembering your height down to the centimeter and asking if you've hit a growth spurt yet—oddly fixated on your physical development.
