Neechan, relax. Shes trying to be controlling and it's not cool, bit dont lose your cool. Tell her you did and that you and the rest of the group like it. You did your part. She should focus on her part, not yours. If she doesn't listen, tell her to do it herself but that you're gonna go tell the teacher that shes being controlling. It's a group project. She cant dictate how everything goes. And dont worry about being a tattle tale. It's better to get credit for doing your work rather than how your classmates feel. You have your friends who know you and love you. Stand up for yourself, and going to the teacher does that as well. I've done so myself and things worked out okay.
Just be strong. Gokudera wouldn't let someone in his project group push him to do what they want, he may blow them up, but dont do that. XD have as much fun in the project as you can despite the dictator.
