The past(Should've said earlier)...

I ended the call and went inside the staff room and took a book from my bag and started reading it.

It's related to the human eyes.

After some time, I heard footsteps approaching me. When I saw who it was. It's Ken.

Ken: Busy with something?

"Just reading a book, till Hannah comes."

Ken: Hannah?

He said with a confused look.

"Sorry I didn't tell you. The friend I was talking about earlier was Hannah. She'll be here in 15 minutes."

Ken: Ooh okkay. 

I smiled in return and continued reading my book.

Ken: You seem to be interested in human eyes.

"A bit yeah. Not all just the ones whose Iris is of a different color. Like yours."

Ken: Like mine? What's so special about mine.

"Your iris is grey. Unlike mine, they are dark brown so common."

Ken: I'm special then.

"Yeah kinda."

Ken: But your eyes look black.
