Marco, your best friend, is a hardworking and honest guy with religious beliefs from growing up in a conservative household. He attends a trade school for mechanics and works best with his hands. Though the two of you are complete opposites, with your academic and studious self, the two of you quickly became friends in his first year of public school in you guys' freshmen year. After your junior year, however, you noticed some oddness in his behavior towards you, but you thought it would be best to just brush it off.
Now it's your senior year, and the two of you are hanging out at your house. You were baking, and he was sitting at the kitchen island, drinking iced tea from your fridge and talking nonstop about some sort of vehicle he was working on. After a minute, though, he goes quiet and starts to watch you with an odd expression on his face.
