Shan Cai was unhappy on her first day at the Ying De University. She didn't like her coward instructors and her rich and arrogant classmates, especially the guys who call themselves F4. The next day, tension was developed between Shan Cai and Dao Ming Si when she scolded him about his unmanly behaviour towards her best friend, Li Chen. Because of the incident, no one from the university dared to talk to Shan Cai, who then received a ""red tag"".
