Chapter 1 (Prologue)

I was abandoned by my parents when I was 2 years old. I don't know the reason why they abandoned me. But there is only one thing I am sure of , My second parent loves me for life. 

Who is this second parent? He is old and without a wife and children, but he cared for me as if I were his own. I treated him like a parent; he gave me clothes, food, and his love for me as his child.

Our lives are simple, just very quiet, prosperous and without chaos. We live near the sea, so our livelihood is fishing. He gave me my own name. He called me Seven because it was a lucky number for him and he said I was his lucky charm.

We lived together for 12 years. In the years we have been together, her condition has worsened every year. I don't know if he can handle another year. So I thought about working so I could take him to the hospital. I don't know if his condition is bad, but he still laughs as if he just doesn't have it.

And the day I dreaded has come. I saw him vomiting blood. Tears dripped from my eyes. My mind went blank and I didn't know what to do. The old man held me as if there was no tomorrow. His last will for me was that I should be prosperous in my life.

That day, I mourned and cried as if there was no tomorrow. On the same day, the whole world was shocked because there was a portal that appeared in all corners of the world.The day of my mourning and the shock of the world is called OPENING.
