10 years later

Hyejin has graduated from university and is now working alongside with her father. She finds it difficult to go back to Korea with tons of paper work to be done. Even for many years, she can't go back due to homeworks and projects. However, she still has the bracelet worn and never forgets Kyuhyun.

As for Kyuhyun, he is now doing his Masters in Kyunghee University. He also became an idol of a famous Kpop group, Super Junior. Feeling that Hyejin has broke her promise, he became upset and started to erase his memories about her.

The summer has begun. But Hyejin still has work to do. Mr Lee felt sorry for his daughter. He invited her out for a cup of coffee at Starbucks. "Listen, dear. You've been working too hard. It's about time you go on a summer vacation. Like going back home to see Kyuhyun," he said. "How can I? With all the paper work and finance issues," Hyejin sighed. "Why don't you let me handle all those? Go home and spend time with your boyfriend," said Mr Lee. Hyejin had a twinkle in her eyes. "You mean it?" Mr Lee nod his head. Hyejin grins at her father. "Thanks, appa." 

And so, Hyejin is released from work. She goes online and booked the air tickets to Seoul. Then, she started packing her luggage. Mrs Lee was surprised to find her packing up. "Where are you going?"

"Home to see Kyuhyun. It's been 10 years since we left. It's about time I go home," replied Hyejin. Mrs Lee began to sigh. "Dear, I think Kyuhyun has forgotten about you. Because you never go back at all. He won't even remember your face."

"Oh, I'm sure he'll remembers me." Hyejin continue packing her luggage. Three days later, she was leaving for Seoul. Mrs Lee bid farewell to her daughter. "Don't forget to contact us." Hyejin promised her and disappears inside. On the plane, she was excited to go back and see Kyuhyun. 

"Attention all passengers. We have landed in Incheon International Airport. Please wait until the plane has come to a complete stop and the seatbelt sign is turned off. Thank you for flying with us. Have a pleasant trip." Hyejin was happy that she is finally home. When the seatbelt sign is off, she took down her bag and follow the line out of the plane. 

She yawns as she scans for her luggage. She suffered jetlag on the plane and didn't have much sleep. On the way out to the exit, she saw Kyuhyun's family waving at her. But Kyuhyun was not with them. Mrs Cho was the first person to hug Hyejin. "Hello. Welcome back."

"She look completely different than before," said Ahra, Kyuhyun's older sister.

"I change my hairstyle," Hyejin told Ahra. She turned to the family. "It's great to see all of you again. Where is Kyuhyun?" 

"He's on his schedules and he can't make it to see you," said Ahra.

"He became an idol and joined Super Junior," Mr Cho told her. "Idol? Super Junior?" Hyejin felt astounded. She doesn't know anything about Kyuhyun's new life because they have never contacted each other since she left. "Kyu never told you about this, did he?" Hyejin shook her head. "We never contact each other."

"It's strange that Kyu never talked about you anymore," Ahra told her. 

"Anyways,
