After Avengers 4, Tony Stark, who sacrificed his life to save the world, came to the first stop after his death. In this wilderness between life and death, he met Bambi. Tony had never thought about it, and had never imagined that one day he would form a temporary teammate with Bambi, the man who stuck his neck and threw him off the building when he failed to invade the earth. They would quarrel with each other all the way, accompany them all the way, support them all the way, and eventually become a bright spot in each other's world.
