To

The air was heavy with the smell of rot and dust. The distant screams of the few souls still alive mixed with the growls of the zombies that filled the streets; in the middle of this chaos, Till ran without looking back, jumping between rubble and inert bodies, but what really drove him to keep running was not the zombies... it was Ivan.
"Till, please wait!" Ivan screamed, chasing him desperately, Till glared. "Get away from me, you moron! I don't want your fucking kisses! Go make out with a zombie instead if you care so much!" Ivan stumbled, but got up immediately, his breathing heavy. "I don't care about the fucking apocalypse, I only care about you!" He screamed, his voice breaking.
Till quickened his pace, fleeing more from the boy than from the undead, the chaos and the zombies were not as terrifying as the possibility of facing Ivan's feelings that he did not want or did not know how to reciprocate, Till turned down an alley.
