I led a life on this planet for almost my whole life. I lived normally, and by normal I mean avoiding overly close contact with human beings. I did a damn good job not getting attached to people, I was doing great in fact... until he moved in, with his dark eyes and looming height. 

Just another neighbor, another person to ignore.

And then he knocked on my door. 

Sungyeol is annoying. Overly friendly. Stupid. We do not get along, at all. But when my pea-brain brother decides to be best buddies with him, well, something... unexpected happens. 

I blow my cover. Our cover.

The masks which me and my brother had worn for all our years on Earth fell. We aliens, had exposed ourselves. 

You heard me. Alien. Yes, my brother and I are aliens, we have a galaxy of other creatures searching for us and wanting to steal our abilities, and exposing our powers to Sungyeol has lit him up like a bogy on a radar. He is now our responsibility, and the only way he's going to stay alive is by sticking close to me or my brother. 

If I don't kill him first, that is.
