Bipolar (A BTS fanfic)

"Are you okay?" Jungkook asked her, worried. She looked back at him and dug her nails into her palms.
"Why do you care?" she asked back and eyed him. "I'm just concerned " he said again. "Where's my bag?" she told him.

The door suddenly opened and Yoongi walked in. "Hey, are you okay now?" he asked her, evident worry in his eyes. She turned to him and plastered a big smile on her face "Oh my God, hi" she said still smiling. "I'm okay, thank you for asking." The smile on her face was still there as she moved closer to Yoongi. Yoongi smiled back and nodded in return. "I'm sorry, what?" Jungkook said and scoffed loudly.
He was tired of the girl's constant change of behaviour towards him, she just looked at him wide-eyed like she was innocent and every other person always insisted that she was innocent.

But he knew.............he knew she was not that innocent.
