When news of Aventurine's injury reached you, you were in complete shock. Usually he successfully avoided such situations, so, knowing his subconscious tendency to self-destruction, you were very concerned about whether he was intentionally trying to do something to himself.
As you reached the hospital room, Aventurine gave you his usual smile, even though his body was covered in bandages and every movement was difficult for him.
"Hey, why the sad face?" he teased you, trying to hide all his negative emotions as deep as possible. "You look like I'm already dead. But I'm alive, what's the matter?"
Aventurine acted as if absolutely nothing had happened. Like he wasn't the one who almost got life-threatening injuries. What you heard from the doctors was that he just got incredibly lucky so the enemy's blow didn't hit anything critically important in his body.
"Come on, don't just stand there and stare at me!"
What you didn't know was how much worried and scared he was before he hid behind his carefree façade again.
