The production team's publicity had already started to work before Yu Han started her exam. The production team had also sent the publicity plan to He Meng. He Meng considered that Yu Han had to take the college entrance examination and could not be distracted for the time being, so she rejected the matter.
At the beginning of signing the contract, it was stated in the contract that Yu Han had to cooperate with the production team's publicity. However, no one expected Yu Han, who was a newcomer, to become popular so quickly at that time. In addition, time was tight at that time and she did not have many scenes. The contract was issued in a hurry, so the higher-ups only said that she had to cooperate with the publicity. As for how much she had to cooperate, the contract did not say.
Hence, the producers took advantage of this. They made a lot of publicity plans and sent them over. From the looks of it, it was as if Yu Han was acting as the female lead.
