There were some things that Su Bai did not know, but that did not mean that Su Bai was unable to guess it. Su Bai did not know if Gu Fan's feelings for Aroma was real or not, but there should be a little,but Gu Fan applying for a posting in a medical research center in London for the sake of Aroma is something that is questionable.
In fact, Gu Fan had always been studying in Europe, it was just that time when the murder club was established, Gu Fan seemed to be pressured by his family's intend for him to work in the country. Thinking of it, Gu Fan should had been overseas when he tuned in to Dreadful Radio and became an audience, seeing how he previously displayed his pair of angel wings, it is almost able to conclude that Gu Fan was considered an audience from the western circles.
Su Bai did not know how Dreadful Radio distinguished eastern and western audiences, was it based on territory or based on race?
