My MILF System! Spending Money On Lewd Items For 100% Rebate!

*JOIN DISCORD!!!!* Jaeho Han's father was his hero. A man built like Hercules who worked multiple jobs to give his kids the education he never had. But after the twins were born, the workload became too much and his father's health deteriorated silently, refusing help, hiding his condition even from his wife. He died when Jaeho was thirteen, leaving behind a grieving wife who could barely look at her children without feeling the guilt as she thought it was the birth of the twins that killed her husband. She tried her best for four years before she disappeared. At seventeen, Jaeho became the sole guardian of his five year old twin sisters, Jia and Serin. He worked multiple jobs like his father to give them a chance at life. School was a nightmare, Jaeho was bullied for being poor, for being an orphan, for being a year older than everyone else due to his late admission due to making sure his sisters' education came first. But he endured it all without fighting back, because one wrong move meant losing everything. The debt piled up at ₩737,500,000. Over $500,000. Loan sharks were on his neck, bills suffocating him. Jaeho always smiled for his sisters, but at night, he was drowning. One morning, he helped a recently divorced woman at his laundromat job. She couldn't pay but promised to refund him once her banking app stops acting up, so he transferred his last ₩50,000 to help pay for whatever it was she wanted. Hopefully, it would return with a nice tip. A cyan screen appeared shortly after this help was rendered.

Jaeho questioned before looking at the woman with suspicion. For the first time in five years, Jaeho could breathe. But the system wasn't done with him yet. Every won he spent on mature, lonely women came back multiplied which meant unlimited wealth. His father told him that as long as you keep moving forward, things will work out. Jaeho's about to find out just how far forward he can go. --------- Content Tags → Smut / R18+ → Harem, Comedy, Slice of life → System-Elements → Slightly towards Netori [Mc stealing and using others wife] → No Yuri → No Netorase / Yaoi / BL → System + Worldbuilding Driven
