"I am someone you can trust. But anyone can say that. I plan to prove it." To keep proving it if he hasn't already. As if being here, now isn't proof. But it's not Yohan's place to decide whether or not Hayun trusts him. He can do what he can to push the boy in the direction, but it's his choice at the end of it.

But this is a good start. That Hayun called him, not a friend closer to his own age, not anyone else. That he didn't want to sit here alone in the dark. That he reached out of the dark for Yohan.

"I want to be someone you trust, Hayun."
