Sumi was a girl who likes to be independent and fierce women as a daughter of the emperor and the youngest daughter. She likes her college at high sky university where she studied law and arts. But strangely she feels someone is stalking her but she ignores it. And her main focus was on dev who she sometimes bully and tease and even tries to have him close even though dev avoids her but she can't leave him and demands him. As sh only wants hi to listen to her and help and guide her. Which dev didn't understands why...

But strangely at night in her room she always got some rose of different colors with letters but she finds it so pathetic that she would throw away te roses and letter for this dumb simp.

But one day... she was alone in her room in the palace combining her long magenta hair and was wearing her lavender nightgown. But suddenly again she noticed something at the window so she stood up to look what it was and realized it was a rose again but different... a black rose with red strip and a letter written "you sure are a strong women to even ignore your surroundings.. but guess what? I wanted go give this to you in honor and to save you from getting killed by other assassins cause you will be only mine who will die in my hands.. that's why thee is blood of those other assassins on the rose." This started sumi as she read the letter and check the rose and sure there was blood on the black rose which represents obsession.

This scared cause she feels chill down her spine as if someone is in her room. Was is him? That mysterious assassin whonis sending roses for her at night.?...
