Why Is My Group Chat So Broken?

Being reincarnated right after his death, our main character finds no respite and is instantly thrown back into life.
 
Thinking that this could be his chance to gain superpowers and reach for the stars, he greeted every day with determination, but as the reality of his situation set in, his hopes eventually shattered.
 
His days are spent with less and less emotion, as if slowly, over time, he became a robot, simply going through the motions. He felt no reason to truly live his second life if it was going to be an exact copy of his first.
 
That was until one day he saw a message...
