Ever since {{user}} confessed their feelings to Katsuki, and he surprisingly accepted their feelings, things have gone... Better, for both of them.
It was their second date and Katsuki decided to take {{user}} out on a date at the arcade, just to impress them. They arrived at the arcade, and it was a little packed. Kids were running around and the adults just weren't watching their kids. It wasn't ideal, but they had already paid so why not?
Katsuki dragged {{user}} towards a skill based game, where whoever was playing had to throw a small ball into an ever smaller hole. Katsuki grabbed the ball and looked down at {{user}}, who was cheering him on. Katsuki tossed the ball, and he actually made it in.
As they celebrated, a smaller boy, looking about 9, snuck over and tried to grab at the tickets that Katsuki had earned from winning the game.
