So can you do headcanons for jealous Peter. Like MJ's had a crush on Peter forever, but they're just friends and she's accepted that. She isn't going to pine over Peter Parker. It's time to put this crush down and the new guy is ok and into her. So she should definitely just say yes the next time he asks her out. Peter is just mind blown when MJ can't hang out cuz she has a date. MJ doesn't date.
