Flashback when Sehun and Sera was still five years old.

“Come on noona! We gonna be late –“ said the little boy with a grin plastered on his face.

The girl just simply nodded and started tying her shoes like her mother teaches her before.

Once they arrived at the camp site near the forest, Sehun and Sera started running around – playing catch with each other. Their giggles twinkling in the air as well their parent’s laughter.

Near the dawn at the time, Sehun noticed something in the wood and being the mischievous kid, he asked Sera to join him explored the woods.
