Actually, Shan Shan has not done anything wrong. Her only mistake is that she is not qualified yet still got accepted by a conglomerate known for its harsh recruitment standards. Graduates from non-prestigious universities are normally not accepted. Also, the manager had in mind someone else better who lost to Shan Shan. The manager is an upright old man who suspects Shan Shan had used backdoor connections so he naturally dislikes her.
