Ok can anyone explain to me wtf happening? My English seems to be not enough to get the plot. Shuli is going on with her duties. Kids are growing. What does church and all these old fucks want? Why the want to kill Shuli? There was a chapter, which showed the past (before Shuli reincarnated), where kids actually wanted to make up with her. And ever since I’m confused as hell ╥﹏╥
