[Quiet, possessive younger seme x polished, easygoing older uke]
Qiao Yuxi was the sort who took life as it came. Even when he woke up to find he had transmigrated into an era of scarcity before birth, with no golden finger provided by the transmigration gods, he never complained. He simply went about his life for twenty years. Then one day, his childhood friend from his previous life showed up, clung to his leg, and wailed that he had a way to get them back. But the System was clearly unreliable: not only did it make the two of them play matchmaker, it also came with a progress bar that usually pretended to be dead and only deigned to react when he and Zheng Yudong interacted.
