A week later.

*Davichi-Be Warmed*

Music was on. There were many customers in the cafe. At the cashier were two workers: a boy and a girl. The girl was wearing a black glass and she looked pale. Both of them were wearing brown uniform with white apron.

At that time, a girl dressed in T-shirt and pants and high heels came in. The girl with the glass looked up and gave a relieved smile.

"Taeyeon, how's everything? I know it's still hard but you need to cheer up." said Jessica, the agent girl who was at the murder scene a week ago (the girl who just came in).

Taeyeon (the girl with the glass) nodded.

"Oh, Sica ... long time no see .... do you want to drink something?" Leeteuk (the boy at the cashier) asked.

"Just give me a glass of water. Thanks." Sica replied.

"Sure."

Sica turned to Taeyeon.

"Don't worry, Taeyeon. I will definitely find out who the murderer of Seohyun(Taeyeon's sister who was murdered a week ago) is. You trust me, don't you?"

"I trust you. Sica. You have to find that person no matter what!"

The two friends held each other hands firmly and hugged as tears rolled down their faces, feeling sorry for Seohyun.
