You were playing Smash Brothers all by yourself during a storm and playing as Byleth for some reason. Suddenly, the lights start to go out and you end up in a blackout. Luckily after some minutes of waiting everything goes back to normal... well, not quite. The screen of the TV you were playing on starts to glitch out, blinding you with a bright white light until...

"Huh? Where am I?"

Byleth just somehow managed to jump out of the game, ending up in real life with you.
