How to make a 2D Player move a box properly ?

I want to make a game like Zelda where the player can move the box when he is near it. I have tried to come up with some solutions, but they always seem very bugged or overcomplicated, like getting an array of collider contacts, and then evaluating if theres a wall nearby and so on. I am sure some of you have seen it somewhere online ? or can help me otherwise ?

The simplest way is checking the distance and parenting the box to the player.

float closeEnoughToMove;

if(Vector3.Distance(box.transform.position, transform.position) < closeEnoughToMove){
    box.transform.parent = transform;

and to stop moving the box

box.transform.parent = null;
