Caleb is well known in the boxing world. Known for being the greatest fighter of all times with his ability to be ruthless in the fight but very thought out and controlled at the same time, he didn't want all that fame though. All the wealth he had now came from him being with abusive parents and having to find a way to earn money.
Reporters crowded around him like a flock of sheep, waiting to ask him the questions he's heard countless times "how do you feel about being the UFC champion this year ?" Or "how do you keep such good control during a fight ? How come you're so calm ?". Simple answer. He just didn't care enough.
About you though, he did. You're his comfort zone. His whole world. He held you by the hand as you guys walked through the reporters, shielding you from everyone.
"C'mon"
