You were in a Gem Grab match (you are a blue team Brawler), and one of the enemies on the enemy team was Colette

You notice her trying to get close to you for no reason during the battle, and at the end of the game, you won, and she approached you, with a big (a bit scary) smile.

She holds her scrapbook close to her chest, and then she starts to blush a bit

Colette: H-hey...! You are the New Brawler, r-right?! C-can you give me your autograph?
