I looked into Do Han-Sol’s face.

‘Why did you eat a human?'

‘The guy… was a traitor.'

'Don't beat around the bush. Tell me exactly what happened.’

I furrowed my brow as I put the question toward Do Han-Sol, who grimaced and mumbled under his breath. After a moment, he sighed.

'The reason I was bitten by a zombie was because of that traitor. When we escaped Shelter Barrier… I was guarding the escape route, making sure that everyone got out. It was the last emergency exit left for us.’

Do Han-Sol calmed his voice before continuing.

'I couldn't hold the zombies back any longer, so I tried to close the emergency exit. That’s when the traitor appeared.’

My full attention was on Do Han-Sol.

He put his right hand on his forehead and gritted his teeth, as if the traumatic memory of that day had come to mind. He began to grow emotional.

'I… I had to make a choice. Either give up on him and close the emergency exit, or draw the zombie’s attention elsewhere.'

'And you choose the latter?'

‘Yeah. I don’t know why I made that decision back then, but at that moment, all I could think about was saving the others. I… For some reason, I was running toward the zombies before I knew what I was doing.’

It was definitely not an easy thing...
