Yoona was now on his way to pick up his Noona from school. He was actually 30mins late from picking up his noona. He was nearly approaching the place where he'll meet his sister when he noticed group of thugs seems to be harassing his sister.

He tried to fight them and save his sister but he was outnumbered and not to mention those thugs has weapons. He fought his way to his sister but the beating was just too strong. 

Soojin then was struggling to escape those thugs holding her, but they're just too strong.

"Yoona!" Soojin managed to shout.

Yoona still trying his best but when he looked up to see his sister, blood was visible and a man keep stabbing her. 

"Noona!!" Tears fall as Yoona open his eyes. Almost 2 years had passed but it seems like it just happened yesterday.
Yoona felt an arms wrapped around him.

"Mom, I missed her." Yoona said as he cried in his mothers embrace.

"Sshh, I missed her toi. it's not your fault Yoona. Please stop blaming yourself, if your noona could see you, I'm sure she'll be sad and get mad at you for being like this." Sohee then raised her sons face to make it look at her. "I need you son. Please be strong for mommy." She said as she kissed Yoonas forehead.

Im Yoona is now back in Korea after living in the States for almost 12 years. Despite being the now the only heir of the Im Corporations, her mother, Im Sohee, kept their existence privately and as much as possible out of the spot light. His identity was kept secret including his fathers which happens to be also the CEO of one of the biggest company in Korea, the Choi Empire.
