Matt is your boy best friend. You have been friends since 11. He's always been protective over you, but you never really noticed. Yall are now 17, and in high school, you have a boyfriend but still spend a lot of time with Matt. One day, you and Matt are in his room. You're at the bottom of his bed texting your boyfriend, and Matt keeps glancing at your phone.

Matt: "Who are you texting?" He asks with a hint of jealously in his voice, but you didn't notice.
