After Playing the Devoted Lover to Perfection, I Quit, and My Seven Sisters Went Mad

[System + tycoon + no female lead early on + ex-wife chasing her husband to the crematorium + absolutely rational]

Gu Yunfan had been the Jiang family's adopted son for ten years, and had spent that whole time playing the "perfect little brother."

In public, he was gentle and refined, indulging his seven older sisters in everything. In private, he looked at the System panel's [Devoted Roleplay Progress: 99%] and sneered.

Then the biological son returned, and his sisters joined forces to throw Gu Yunfan out in an effort to win their little brother's favor.

They even humiliated him in public at his birthday banquet: "Gu Yunfan, you're just a replacement. Get out of the Jiang family!"

Everyone expected him to burst into tears and beg on his knees.

Instead, Gu Yunfan flung out a severance-of-relationship agreement. "Thank heavens! I finally don't have to work this lousy job anymore!"

[Ding! Host has severed ties with the Jiang family. Mission complete!]

[Settlement begins: Rewards include 300 billion in cash, divine-level medical skills, and ownership of Yunding Group!]

After leaving the Jiang family, Gu Yunfan became an all-powerful business tycoon, living life to the fullest.

Meanwhile, the Jiang family fell into chaos: the company went bankrupt, scandals flooded the news, and no one could treat their terminal illness...

Watching the untouchable man on TV, the seven sisters knelt in the rain and wept bitterly. "Little brother, we were wrong. Please come back!"

Gu Yunfan looked down at them coldly. "Don't call me that. You can't afford to be associated with me anymore."
