Sweat dripping off his face, he was wore out. His legs were about to give up but he kept on dancing. He wants every step to be perfect. He was repeating one particular step again and again, because he kept getting it wrong. He groan and fall on the ground. He couldn't feel his legs anymore.
"Jungkook, rest for some time. I will help you late to get this step right." Hoseok said. Jungkook smiled through all the exhaustion.
"Hyung, I am okay." He exclaimed drinking the water bottle.
"Jungkook, Eunjin is here."
His face light up here that name. She was standing near his practice room. "Eunjin!" He stood up and run to her. He hugged her. "Where you been for all these days? I missed you so much." He exclaimed, then she started crying.
"Eunjin? Why are you crying?" He took her outside, since she said she wants to talk to him in privacy.
At park,

"Jungkook, I am pregnant." She told him while crying. Jungkook was stunned, he is just 15 year old and he is just an trainee.
"But we only did once-"
"Jungkook? Are you doubting me? I am pregnant with your baby. What to do now?" She hide her face in her hands. "I tried to do abortion but-t I can't abort because of some complications. My mom will kill me. I know you gonna leave me too." She cried more.
Jungkook hold her hand and sit on the ground to get a better look at her face. "Eunjin, please don't cry. We will find a way. You will not gonna raise this baby alone. I will be with you."
