Spending on My School Beauty Bestie Returns Tenfold

After being dumped by his gold-digging ex-girlfriend Su Ya for being poor, Lin Chen awakens a 'God-level Consumption Rebate System' that gives him ten times cash back for every penny he spends on Su Ya's aloof school beauty bestie, Xia Wanxing! In the opening scene, he splurges 500,000 at the mall, slapping his ex in the face; then he invests in his bestie's studio, dominating business across all fields. As Lin Chen's wealth skyrockets from campus tycoon to capital giant, Su Ya finally realizes what she lost and begs for reconciliation in the rain at night. But Lin Chen just sneers: 'Get lost, don't delay me from spending money on Wanxing.' — Description from novelcodex.org
