Yiwei and Michelle first crossed paths at a postgraduate Bible study while both were grappling with their PhDs at Sydney University. At the time, their interaction was short, and entirely uneventful. Shortly afterwards, Yiwei departed for the United States to continue his studies, and life carried on.

Two years later, God brought them back together, through a mutual friend's wedding in Sydney. By this stage, Yiwei had rediscovered the concept of exercise after several years of treating his PhD like an long term extreme endurance project that required minimal physical activity. Having recently taken up running and cycling, he was feeling quite pleased with his newfound athleticism. It was during this reunion at their friend's wedding, that Yiwei had the brain space to notice Michelle properly for the first time. Realising she was an economist, he bravely initiated conversation by asking her about ETFs and investing (possibly on purpose, likely by accident).
