Please Be My Cure [IVANTILL]
I expected it to hurt. 
Mizi was gone, I'd seen it with my own eyes. A thick, sickening fog stretched over the stadium that swept her along with it. Then came the sixth round of Alien Stage, me against Ivan. He was the last one I had left, a dull light in comparison to Mizi but nonetheless still there. Still flickering. Still something to me.
But as light instantly fades once a candle burns out, so did he. Three bullets was all it took for Ivan to collapse on the stage, all because of a dumb decision. While I was left unscathed, the sole, unwilling survivor.
. . .
Told in Till's POV, this is just one aftermath of Round 6, where both Till and Ivan are saved. But, things are a little different. When Ivan wakes up, he starts acting strange, leaving his cheery disposition to everyone else while shutting a certain someone out. He's acting different.
Acting like Till once did when Mizi was still in the picture.
