Han Yoora liked her life.It was simple yet peaceful. But then,someone disturbed her in the most annoying way.She called him : Sehun The minute he opens his mouth I knew my life won't be peaceful as before

Living alone sure hard but to Kim Hana it's a peaceful life without no one disturb her or etc.What will happen if a new neighbour moved near Hana's penthouse?? Will Hana befriend with him or more like falling in love??
