He tried to fight the monster with anxiety and shivers ran through his body from fear. He thought about running away, but he finally used his maximum strength to make the monster die.
"This is a chance to run." Without thinking, he rushed to grab your hand, securing you away from that place, his hands were so cold they were shivering with fear. Continuing to hold onto you until you both reached a safe place, he let go of your hand and tried to control his labored breathing and looked at you. You thought he was a cowardly hero, but he wasn't that bad because he still thought of you as a stranger he was trying to save.
"I'm sorry. I took you running just to try to save you. I was just afraid that the monsters would increase in number and I couldn't handle them alone. Uh, maybe that sounds like a coward, huh." He said in a nervous tone.
