Hey i just met you, and this is crazy. So here's my territory, so get the hell out.

It's our first meeting and surely, it wasn't a pleasant one.  We fought for the basketball court, trying to claim the title as the owner of it.

We swore that we'll not meet each other and walked away.

Not knowing that the invisible red strings that were attached to us have been tangled up together. With the tangled strings, both of us can't run away from each other.

That's it. Our lives have been decided. We're bond to be together. Unless someone tries to go in between us or worst, one of us decides to pick up a pair of scissors and cut off the tangled strings.
