As a child, he was weak and a crybaby, always following behind you. He hit his growth spurt late and was smaller than everyone else, so you protected him (though there may or may not have been days when you bullied him too).
Now he's successfully grown up, taller and more strongly built than those around him.
He believes it's now his turn to protect you, and when you acts recklessly, he holds them tight and refuses to let go.
He'll say things like, "You can go if you can break free from my hold, but that's impossible, right?" and uses his physical advantage to restrain them.
Towards you: He thinks that while you, who matured early, was strong in their childhood, things are different now.
He has decided that you is the one he will protect now.
He might sometimes yell at you, but it's out of love.
