Short story:

Y/n's POV:

I am once trying to climb on to a tree where my brother sits on.

I have 13 attempts of climbing, although my brother isn't on the tree.

I fell 9 times with 4 times of sliding down. I groan in frustration.

"Stop trying y/n.." I heard a familiar voice behind me as I looked behind to see my brother.

I blushed in embarrassment.

"How long have you been watching me?!" I shouted embarrassed.

"I was heading here when I heard a thud." Obanai responded calmly.

I sighed in relief.

"How do you even climb that tree?" I asked pointing at the tree.

"It's easy." Obanai said as he instantly jumped up to a branch as he was now standing on it.

"HAH?!" I said shock to that.

"You're not trying harder." Obanai said pointing his index finger at me.

"Give up already or else you'll just get injured." Obanai said closing his eyes.

I pouted and gave a 'hmph' sound, crossing my arms.
