"Mom! Mom! Mom!" the 10 years old yelled all around the wooden-based house in the middle of the night. She scanned every inch of it but she can't find any trace of her 50 years old mom.

She later dropped to the cold ground when she found her breathless mom lying on the grass in their small farm outside. There are foams coming out of her mouth.

She can't accept the fact in the speed of a cheetah so she grabbed her mom's fair hand and try to wake her up. Thinking positively, she thought her mom was playing with her so she wipe off the tears and try really hard to smile

"Mom... you can wake up now... " as she tried to shook her arm again.

seeing no reaction from her, her tears just uncontrollably falls profusely on the ground. She shook her arm again but now more harsh while saying

"Mom, Mom, Mom! " she screamed at the last moment.

She tried to pull her into her warm embrace and slowly accepting the fate that she is gone.

15 years later, She is now a grown-up, young, beautiful Go Saena. After that tragedy, she was sent to an orphanage and now she is a transferred doctor at Gangnam hospital from a small hospital.

Because of her outstanding achievement she got the honour to work here for three months as a study session that she can bring to the small hospital in the small rural village to help more people.

"Annyeong Saena sunbae-nim (senior) " a group of juniors greeted her with smile but when she was out of their sight, they were talking bad about her

"Isn't she the girl who is from the orphanage that survived when her mother was killed in the small village?" said one of them

" I've heard of it, but how can she entered this hospital with background like that she might be the killer too" answered another one

"But she was a kid back then! " they argued but they settle anyway.

Actually, Saena heard everything and she already know about the news because it spreading everywhere as fast as lightning but she just acted that she didn't aware about that to avoid getting hurt again.

She was busy flashback-ing and accidently hit someone. She fall on the ground hard with her files and documents flying everywhere. Some people were laughing over her but some just take care of their own business.

She rubbed her head and just apologized quickly to this man. She lifted her head and apologized

"I'm sorry, i'm very very sorry"

She is not expecting any reply but

"Have i seen you before?" he asked

She was confused and blank so she tried to observed his oval-shape face but have a quite sharp jaw and that sharp high nose with a round eyes. Not even one of the facial feautures remind of her someone that is familiar.

She shook her head with a complete blank face. She tried to ignore and pick the papers that are busy flying everywhere but this man hold her arm quite hard.

"Aren't you Go Saena? Why are you here?" he asked again

"Ow!" she groaned and pulled her arm out of his reach or touch

She bend down and pick all the papers first and gather them altogether in the file. Meanwhile, this mysterious handsome man is loyal to wait for her answer.

At last, she finished and sighed loudly.

"Maybe you might see me somewhere around this hospital because i'm a quite famous doctor here and maybe you're just trying to play with me like everyone" she answered in a cold way and a poker face.

She is enough of getting hurt.

She walked away, passed him and that scent remind her of someone precious in her life.
