Su Xin actually did not promise any special privileges initially, he only mentioned something about the other party being considered a founding member of the organization, which was just an empty statement. However, this empty talk might have a certain connection with the so-called promise of privileges, maybe misleading Lin Yufei so that when she hears the term 'founding member of the organization', she vaguely feels like he indeed said something like that, which leads her to believe he truly promised special privileges.
After Su Xin finished speaking, he noticed Lin Yufei merely thanked him seriously without any trace of recalling or pondering, as if she never considered if Su Xin truly said those words.
The notification sound from the system didn't ring either.
