The four stars lent their faces to a promotional poster for the campaign, looking sharp in tailored uniforms. SMPA uploaded this picture with a message on their official Facebook, informing people that they have extended the date for people to submit their ideas for an anti-school violence skit.�

The message reads, "Thank you to everyone who participated in the contest for anti-school violence skits~ Due to the overwhelming number of participants, we had to pay more special attention to the picking of a skit and push back the date of our winner announcement to April 4. We're sorry about making you all wait. April 4! We will meet you with good news~"�
