You got the little bird ending, in that end it's not actually Mei, it's Kimi! They changed bodies and Mei is stuck in the game. Kimi took a bus to run away from home so she could finally experience what it was like to be free (away from people who could soon find out she wasn't Mei and force her to go back to the game)
