One gloomy afternoon, Seohyun was walking around in a certain park in Incheon. She was talking pictures of random things that can be found in that park. She roamed around the park and saw lots of people coming for her. Some were asking her for a picture and some wanted her autograph.

Hours passed and Seohyun got tired. She decided to eat something since it's almost 7 in the evening.

"What to eat? What to eat?" Seohyun said.

Finally, she saw a restaurant nearby.

"Finally! All I have to do is to cross the street. Yes!"

She was about to cross the street but suddenly, she saw Donghae walking at the other side of the street.

Seohyun tried to hide but it was too late. Donghae already saw her.

"Hi Seohyun!" Donghae shouted and started to wave his hand to catch her attention.

Seohyun didn't know what to say or to do so she smiled instead of saying hi.

After that scenario, Donghae started to walk away.

Donghae happened to walk inside a certain store. 

He bought something and went somewhere else.

Donghae is nowhere in sight.

The next day, Seohyun went to a dance studio and spend the whole day practicing.

As she was walking, the sun is shining brightly and she can see smiling faces from other people passing by.

"Good thing I brought my sun block with me." she said.

She arrived at the dance studio at 9:47am.

She saw Taeyeon, Tiffany, Yoona, Yuri, and Jessica getting warmed up.

"Ya! Chinggu!" Taeyeon shouted from afar to Seohyun.

"Annyeong! How's everybody?" Seohyun replied and asked.

"We're great actually. ^___^ Our manager called us to practice today. But the other girls are on vacation so they can't practice with us at the moment." Taeyeon replied.

"Oh, I see. Well, I guess we still need to practice even if we're incomplete. Let's do some warm ups first." Seohyun replied.

Seohyun and the others started stretching and did some vocals.

They first practiced dancing Hoot then Run Devil Run.

It took them almost 3 hours to master each of their songs.
