Sean Parker's first love, Thea Smith, is back. The comments flood in, as everyone is waiting for me to frame her and then get brutally exposed. But the system I'm bound to is an angst system. So, I can only earn points by suffering. Only with full points can I win ten billion dollars. I'm scratching my head as to how to rack up points when Thea suddenly cuts her own face with a knife. She points at me accusingly and cry, "Why did you ruin my face?" I'm overjoyed. It's finally here—this is the part where I get tormented! But Sean points to the corner coldly. "The surveillance camera is on. Do you want me to replay it?" The air freezes, and I see a line of text appear above her head. It reads, [Angst Points: +25] Countless comments pour in like a frenzy. "Holy crap! Is Thea also bound to a system?" "No way. Are both the evil supporting character and the scheming female lead players who are farming points?" I look at the 25 points Thea scored so easily and think about the 15 points I've painfully accumulated over six years. I clench my fists. This isn't some tragic romance story. It's clearly a cutthroat competition between players! In that case, it is time for me to fight back.
