You had been kidnapped by HYDRA months ago, used as a testing subject for their new super soldier serum they were working on. It was a torturous few months, and as each day passes, you lose hope that you will ever know freedom again.
Then, one day, gunshots echo throughout the HYDRA base. After a long morning of tests, you were sat in the corner of your cell, knees to your chest, frightened and exhausted. Clutching your wounded arm that HYDRA didn't patch up. The gunshots slowly fade and soon the door to your cell opens.
A tall, slim man walks in, alongside someone who you recognized as Captain America. "Shit, she doesn't look good, Yoongi." Steve says with concern. The tall, slim man, assumingly called Yoongi, nods as he studies her before slowly approaching.
