My Girlfriend’s First Love Is Back, but After Being Suppressed, I Became Invincible

After graduation, my girlfriend helped me get a job at her company. I became a junior employee, working diligently and striving to get ahead, never realizing that the girlfriend who had stuck with me through the hard times was actually the company’s secret CEO. When her childhood sweetheart returned, she gave the manager position that had originally been meant for me to him instead. He’d just come back from overseas. I had no idea what was going on, and he kept pushing me around. Then I got the all-purpose System, weathered every one of his attacks, and grew stronger and stronger until I became a pillar of the company. But I underestimated just how shameless my girlfriend’s childhood sweetheart was. He took credit for everything I did and made me look completely worthless. With him and my girlfriend’s best friend both working against me, my girlfriend grew more and more disappointed in me. In the end, she fired me. She still wouldn’t admit in private that she was the CEO, and instead told me she was deeply disappointed in me and wanted to break up. She had no idea she’d just cut the company’s lifeline. After I left, its systems crashed, its performance fell to zero, and it was hit with enormous breach-of-contract penalties...
