I have seen raws and used google translator. So what I have understand is that Nan Nan didn’t love Xin Yang’s big brother, he was definitely in love only with Xin Yang. But he had good relationship with big bro and it seems that he told him about his feelings for Xin Yang. So he was just good listener. But idk about brother’s feelings, maybe he just cared about them
