Lee Hana is an eighteen year old girl. At the age of eighteen, she has already experienced numerous emotional breakdowns and fears that are very hard to explain. At sixteen, she lost her parents to a still unknown murderer. At seventeen, she was briefly involved in drug activities. She was a delinquent but not because she wanted to, but because she was forced to, by her ex-boyfriend, Junhyung.

But now, she has decided to start a new life. She has transferred to a new house, to a new school, changed her appearance and even her name, thanks to her cousin oppa, Heo Youngsaeng. Plus, she didn't move alone, she has her best friend, Lee Ji Hoon, with her. Jihoon knows about her past, has already been with her ever since they were ten years old. He was there for her when her parents died, helped her when she needed some, stayed with her when she was alone and also.. he has feelings for her.

However, starting anew is not going easy for Hana. She knows deep inside she isn't completely going to start 'anew'. She knows she still has the fear of being chased by Junhyung after they found out she was planning to report their activities to the police (before she ran away). She knows sooner or later, Junhyung would find her and bring her back to her terrible past.

In addition to that, starting anew at her new school, Woollim High, is not easy for her either. Transferring school, her wish is to be invisible so she won't have to explain about her real identity, her past and just.. her life to anyone. She wants to stay hidden forever and finish her final year properly and problem free.

But her wishes are crushed after one of the school Kingkas, Infinite's member, Kim Myungsoo, starts to have feelings for her and sticks to her like glue. Being so close with the school Kingka.. hmm.. way to stay invisible, all right.

So will Kim Myungsoo be able to win Hana's heart? Will she be able to forget her past? Will she ever be able to get rid of Junhyung? Will Hana finally be able to really start anew?
