Yoona is 19 years old girl, currently studying at Dongguk  University. She always seems to be cheerful person, well-liked by everyone. But, nobody knows what she really is behind the scenes. (Let's pretend Yuri and Yoona are both sisters okay?^^)

And choi Minho is the one who's going to make her walk out of that path and light up her life.

Kwon Yuri, what is she to Yoona? How is things going to change when she appears?

Note: Still trying hard to get more inspirations, this is my first time writing, so bear with me, okay? :)
