"Who are you guys? Where am I? Who am I? What is my name? Why did I get here?" asks Seohyun as Luhan tries to comfort Seohyun but she avoids him

"Don't touch me! You even don't know me!" says Seohyun 

"Hyun-ah, I'm your friend, Xi Luhan. The one who will teach you when you don't know?" Luhan answers

"Mianne! I really don't know you guys! Can someone explain to me where am I and why did you guys here?" asks Seohyun

Suddenly, the door open by Krystal and her family. Seohyun starts to dizzy around. 

"Seohyun-ah? What's wrong with you?" asks Mrs Jung

"S...Sh...She..." says Seohyun and points to Krystal as everyone look at Krystal

"Wh-Why-What's wrong with m-me?!" asks Krystal 

"I...I...I hav- Ouch! My head is hurt!" says Seohyun and holds her head

"Seohyun-ah, go back to sleep. Just forget about all things first." says Myungsoo as he lays Seohyun on the bed and put the blanket on her chest

Seohyun tries her best to sleep but cannot. It still midnight. When she looks around, the others already sleep at the couch. Some of them back to house. Seohyun saw Myungsoo is sleeping, while sitting on the chair. His head on the bed. Seohyun looks at him and slowly touches Myungsoo's hands. 

"If someday I'll find my first love." mumbles Seohyun

When she said the first love word, her head starts to dizzy. 

Flashback 

"Kkamjong-ah, did you know? You are my first love but not my real love." Seohyun wrote it on a book

End Flashback

"Ahh.." mumbles Seohyun and holds her head 

Kai suddenly wakes up and saw Seohyun in pain. He quickly go towards Seohyun.

"Seohyun-ah? Kwaenchana?" asks Kai as Seohyun looks at him

"Can you explain me who am I?" asks Seohyun 

"No, or not you'll be more in pain. Just go sleep." Kai answers, actually he wants to tell Seohyun but he don't want to see Seohyun in pain

"Arraso.." says Seohyun and go sleep back

Day by day, Seohyun still cannot remember her all memory. She just remember her name, parents and house. Yeah, her parents and her brother already back when they knew that Seohyun has an amnesia. One day, Seohyun want to give Kai a bouquet of flower. Because Kai won the basketball competition early. Seohyun calls Kai and tells him to wait her at Han River. S
