My System Has a Bug

The campus belle is my ex, and my friends have grown distant from me.

A System from the start. What? Everyone has one?

One weapon from the start. What? It broke? Then I'll get another one!

I can't take first place on the level rankings, but I can kill the person who did.

You say there's a bug in my System? Sorry, it's being fixed. When will it be fixed? That depends on my mood.
