While in class at school, a zombie attack broke out. I fled desperately and hid in a classroom.

As I was hiding with bated breath, I heard a knock on the door. I peeked out and saw Ha-yeon standing there.

I hesitated because we hate each other, but I opened the door anyway. We waited in silence for the zombies to move away.

Once the zombies retreated, I breathed a sigh of relief. Then, she slowly opened her mouth.

...Thanks, you idiot..
