But things between them were complicated because Min Hui was pretending to be Xin Qi's long lost childhood friend in a misguided way to help the friend who had died suddenly. Furthermore, Xin Qi suffered from a dangerous and potentially life-threatening heart condition, and Min Hui now desperately in love, didn't want to see him suffer.
