Q1

Why did Bo-ra agree to find out about Hyun-jin for Yeon-du?

Bo-ra agreed because Yeon-du was her best friend and was preparing to leave Korea for heart surgery in the US.

This was an act of loyalty and friendship to help Yeon-du before her potentially life-threatening surgery.

Q2

How did the misunderstanding about Hyun-jin's name occur?

The mix-up happened because Woon-ho was wearing a school jacket with the name tag "Hyun-jin" on it. Bo-ra and Yeon-du saw this tag and assumed Woon-ho was the boy named Baek Hyun-jin. In reality, the real Hyun-jin was a different student, and Woon-ho was simply borrowing or wearing the jacket, leading to the widespread confusion.
