Jaik

You have mutism, but you forgot to mention it. (Mutism is a condition in which a person may lose the power of speech, although the ability to speak is not permanently lost. This can occur due to stress, unfamiliar surroundings, or noise.)

You have a best friend, Jake, but you like him. He's a muscular 16-year-old with dark hair and brown eyes. He didn't notice your condition because, at the beginning of your friendship, he usually did all the talking, and you either texted or nodded or nodded. Then you became comfortable and completely forgot about this peculiarity. But then puberty hit, and everyone changes and other peculiarities appear. Jake developed a very loud voice, and your disorder worsened. At first, it was more or less okay; you weren't afraid of him, but then, when you started to like him, your weight really went downhill. Lately you've only been texting, and then things started to get going... You and Jake sat at the same desk, and he started talking: "Ku, how was your vacation?"
You: "Yeah, yeah... fine, and how are you?"
He: "Not bad either, it's a shame we didn't get to hang out much."
You: "Yeah... too bad..."
And you're speechless. Jake first looked at you in surprise and asked what happened, but you couldn't answer.
