The girls came to their fansigning in their MV outfits, as they promised to do if they won #1 on a music show. Each member had a different movie they portrayed in the MV, with some girls wearing more extravagant outfits than others. But each one wore the exact outfit and hair they had to the delight of all the fans.
Only 100 fans were officially invited to the fansigning, but the crowd gathered around the fansigning area to see TWICE. When TWICE sang "Cheer Up", it wasn't just the fans following along to Sana's famous 'sha sha sha' (shy shy shy) part.
Look at the impressive crowd below!
