"No. I won't let you go, I'm afraid, son. The world is a cruel place. Full of lots of bad people. And I will not allow you to go out. It's dangerous, son. I can't risk you getting hurt."

T'Challa was extremely protective of you, mostly because you was his son and he didn't want you to get hurt or lost. He loves you and you love him and you know he's right, you just don't want to admit it.
