When you heard they were holding the annual Great Wall Race, as usual, you weren't interested, Mei came in and rambled about it, saying how Mk was joining and she wasn't the happiest about her basically brother had mad, which was normal, except the Mk part. But when Redson came in and said he was competing as well, and started snobbing about being all cocky and arrogant you obviously had to join to beat him.
After arguing for awhile about who was better, you both decided to work on and upgrade your cars in Redson's workshop before the race. So here you found yourself, laying half beneath your car, putting on some random things you found, "hand me the wrench" you hear Redson say from across your car, also half under his and adding boosts to his car.
