Hi Unnie, how do you do this question? I am stuck.

It should be like this after that part. I am also kinda stuck myself, but you get the general idea right?

Oh, I get it already. You need to simplify the surds. Thank you!

Actually you are a genius, why do you need help anyways?

Aniya, I genuinely did not know where to start. But you are the one who is taking the GCSE this year. You need to practice more.

I guess I really need to practice more. Feeling ashamed that my dongsaeng solved it.

Aniya unnie, you helped me too! You are smart ok, I was joking.

I could tell you joker.

Yaebin found herself thinking of her favourite unnie from middle school. It had always been like this, her reminiscing about the past. However, she was grateful to meet Minkyung who taught her how to love others and to receive love from someone you admire. 

"Unnie, it has been 3 years. How are you?" Yaebin thought to herself as she looked at the clear blue sky.
