I'm not sure which novel or storyline you're referring to. However, according to the information you provided, the Lu Han novel with the female protagonist Xia Moxi involved running men. This might be an online novel or TV series related to Running Brothers. But I'm not sure if this kind of plot really exists or if there are similar contents in other novels. If you have more specific information or want to know more questions, please let me know. I will try my best to answer.
