Zero left without looking back at who those people could be. This type of people is common in the dungeon and Zero could not care less about who those people are.
"DAMMIT! He ran away."
"How did he know? We have made a perfect situation to get him."
The two men who were waiting for Zero to jump in and try to save the girl were angry. They had planned to attack him sneakily while he was trying to save the girl.
"KYYYYYAAAAA!"
The girl, unaware of the fact that Zero had already run away from that location, kept shouting for Zero to come rescue her.
"Malty, stop shouting, he is already gone."
Annoyed, he shouted at the girl who was already making the situation more annoying.
"Huh? What? What happened?"
Confused, the girl asked the two men. She thought the boy was already in their grasp since he appeared.
She was confident that those men who saw her in distress would not think twice before jumping in to save her.
