Black's identity was still unknown to all.

No one knows.

No one could kill him.

His main targets are the ones who were powerful and rich in Korea.

Nothing more, nothing less.

No one knows that he is currently studying in Seoul university.

What if they finally found out his secret identity?

What will he gonna do next?

Your mother died after giving you birth. The person that you trust the most is your father and Hongki. You have a very complicated life. It's hard for you to socialize with others because your father doesn't want you to interact with others so much. You always love to tease or make Hongki be mad at you. You are very obedient to follow what your father wants you to do. You know that he knows what is best for you and Hongki. But.........

You are still curious about your past...

About your childhood life..

Hongki knows that you had an amnesia before but he doesn't know what exactly happened that time....

He doesn't tell you about that.

Your father never tell anything about your past also. He keeps on changing the topic...

..... You've decided to seek for the answer to your question........

But when you finally know the truth, it was too late

TO CHANGE WHAT IS ALREADY DONE......

You've study in abroad for 4 years and went back to Korea to study again...

A whole new chapter of your life is beginning in Seoul University.

You've met the Infinite group that are very nice to you. Well, not all of them.

 You've also met Hyuna who became your bestfriend.

Your friendship is really complicated.

Many crazy things are starting to happen again.

Black, after a long time of absence, is creeping out again. 

You, together with Hyuna and the Infinite group,

Will solve the problem.............

But the question is...... HOW ?
