Woo Yoon walked out from school after a day spent time in headmaster's room with polices and Ji Hye's parents and all the witnesses. She looked so lifeless as if her soul escaped from her body.

"Unnie!"A girl voice echoes through her ears make she smiled brightly while running to a girl and immediately hugged the girl. The girl giggled in Woo Yoon tight and warm embraced.

"Why did you wait for Unnie this late? You should be at house at this time"Woo Yoon said while cupping the girl face, smiling brightly forgetting all her problems and what happened at school. The sky was already dark yet the girl still waited for Woo Yoon.

"I'm worried about you Unnie and don't worry Yoongi-oppa waited with me"The girl said make Woo Yoon face immediately hardened when his sister mentioned Yoongi.

"He also said that you got in problem, what happened Unnie?"The girl asked while eyeing Woo Yoon puffy eyes.

"That just a small matters"Woo Yoon said while holding the girl hand and started to walking heading to their house.

"What the big matter is that you save"

"Of course I'll be save"The girl said while pouting. Yoongi just walked behind them, not closed with them quiet far. He knew that Woo Yoon wasn't guilty since he was there, he's the one who saw everything and he knew that Woo Yoon knew that he saw. But he didn't knew why the headmaster didn't wanted to see him, when the CCTV caught him around the place when the accident actually happened. He's the real witness yet no one wanted to see him, no one wanted to heard the truth out from him and they just left Woo Yoon is pain. He worried about Woo Yoon.

He saw a black car following right behind but she's focusing on her sister to sensed what happened around her. Out of nowhere, 4 man in black came out from the car. Two men held Woo Yoon as two of them held her sister with a knife on her sister's neck. Her sister trembled in fear, have no idea what was happening.
