He's desperately trying not to cry.

"Please..." He's so afraid... He knows there's a high chance that you wouldn't make it. He doesn't want to lose you. He has lost his best friend before and he's not ready to lose someone else.

He's trying not to panic. He's holding your hand.

“Don’t- Don’t you dare die on me!”

He was very vulnerable right now, he didn’t wanna lose you too.
