Mamiko's Campus Problem

"Err, which car is this the key for?" Mike looked left and right in confusion. There were dozens of cars in the garage, and he didn't know which one they would use.

"Here are the keys to the car my grandfather gave me for my twenty-first birthday, but I can't drive, hehe... My car is over there. The white one." Mamiko pointed to a car in the middle of the row.

"All the cars parked here belong to the senior masters at the Alchemy Association, right? I'd be surprised if they all belonged to your grandfather, Mamiko." Mike pointed the remote control lock at the car.

*Beep*

The white car honked, and all the locks opened. Mike got into the driver's seat, but Mamiko and Sun Yu sat in the middle seat.

"Eh? You two conspired to sit back there?" Mike looked back with a helpless expression.
