*BAANNGGGGGGG!*

The door burst open which startled the girl playing on her phone.

"YAAAAAAAAH!! Eonnie! You shocked me to death!!"

"Do you have anything to do tomorrow?"

"None, I guess."

"Good. We're going somewhere."

"Where?"

"Lotte World."

"Why so sudden? Don't you have class tomorrow?"

"None, because of the ongoing Student's Fair."

"I see. But I thought your the organizer of it."

"Yea."

"Then why are---"

"Yul is going on a date tomorrow with another girl." Jessica said, sulking.

"Ah, I see. So, are we????"

"YES! We're going to stalk them!" Jessica do a fist pump. Krystal just sighed to her obsessive-crazy-freak sister.

--------------------------------

Yul meet Taeyeon's parents. They introduce themselves and talk nonstop to know about their families whereabouts. Until Taeyeon came down from her room looking cute with her casual outfit and her hair tied in to pigtails. Yul jaw drop, he never thought that Taeyeon looks so cute far from being a serious type in school.

"You're done? Yul has been waiting for you for years." Mrs. Kim said.

"Yea. I'm sorry." Taeyeon said while sticking her tongue out.

"Anyway, let's go." Yul gestured her out. "Auntie. Nice meeting you. I'll inform you if my parents would visit Korea."

"Ok. Yul, take care of your cousin. Be safe."

They both exited the Kim's house. Yul open the car door for Taeyeon, he run to the driver's seat and then start the engine.

"Now, I know why Miss President is head over heels for you." Taeyeon spoke.

"Huh?"

"Your a total gentleman."

"It's human nature, especially for men. Anyway, why looking so cute today? I never thought that you could wear like that."

"Is that a compliment or an insult?!" Taeyeon glared at him then stop and look at the window side. "Well, You'll see later." She smirk, thinking of something fun.

------------------------

Meanwhile,

Krystal and Jessica is wearing a sunglasses, a cap, mask and anything that they can wear that would prevent them from being discovered. The two keeps on waiting for the "target" until they finally spot them from the crowd.

"Eonnie! They're here!"

"Shhhh! Don't be to noisy!" Jessica hissed to her sister.

"Wow, eonnie, she's so cute. I think that's why Yul oppa agreed to the date." Observing the girl whose with her oppa.

Jessica remained calm. Preventing herself to grab her sister's hair.

"Look! She's clinging to him! Omo! Omo! They look like a real couple." Krystal giggled in excitement. But Jessica is now clutching her fist. Still holding her anger.

"OMG!!!!! They are holding each others hands! They should just get married now!!!!" Squelling like a fangirl. That was it! Krystal has pushed her to her limit. Jessica abruptly stand up and glared at Taeri's fangirl.

"Do you want me sew your unstoppable mouth just to make you shut up?!! Huh??! Jung Sooyeon?!!!" Jessica burst which startled the younger girl and caught the attention of the some people around their hidding place. Krystal pull down her sister and make her calm down.

"Eonnie! Don't take it seriously! Aish! I think they saw us now!." Looking at their targets but guess, they didn't notice them.

Little did they know, Taeyeon heard Jessica's voice not from far away. She smirk. I knew it! She would come.
