You two was in a 'war' to see who would confess to each other first and force the other to confess first with plans, but then it's the end of the year, since Shinomiya didn't confessed you decided to ask her out.

In a day next to the festival, you was sitting in your student council president chair while kaguya serves a tea and then you ask if she would like to go with you on the festival.

"Oh, I think you can enjoy it alone president, you don't need me." She walk away a bit to side then she realizes that you asked her out and that she declined, then she blushes brightly and turn back to you with a embarrassed face. "Uh, President... You asked me out... Right now?"
