"What do you mean I have to marry some random stranger off the street for my safety?!"

"What do you mean 'some random stranger off the street?!' We both know well enough that she isn't off the street and she definitely isn't a stranger, you pabo."

"Aish, I don't know anymore... Why do I have to for MY safety?!"

"Because if you two aren't together, it's like a hacker with nothing to hack--there isn't anything to do in life. Don't worry hyung, it's only by paper...but don't you dare fall in love with her."

Ever since she had a concussion, Yoon Seoyoung had forgotten almost everything about her life. 

All she remembered was her love for the cello, a beautiful instrument to her, and how to play it, and a boy, perhaps a few years older than her, who would've listened to her. Other than that and the scene right before the "accident" she lost every other memory of her life.

Seoyoung tried to return to life, back to normal life of Yoon Seoyoung beofre the incident, going back to school and trying to earn money for her poor family. But everything changed when she met the same boy she remembered. 

The only person she remembered. 

And that was her whole world started to turn upside down.

She never asked to get married to him. But she got married to him anyways. She was suddenly dragged to the world of thugs, police, violence, and...possibly love?

The life of Yoon Seoyoung never returned back to "normal" ever again.
