My life is a roller coaster ride...!

What will happen when a rose will bloom in a bullet.... A story of an innocent girl, whose innocence and cuteness is easy to attract anyone, but will this be enough to melt a heart made of stone? Will this be enough to win the heart of that cold man whose life starts with guns and ends on bullets? An amazing story of a simple girl who is even afraid of a needle... And a mafia guy who kill people on his daily basis. What will happen when their paths cross...? Will her innocence melt his heart or will his cold nature break her into pieces...?
