Your life was quite boring. You worked a 9-5 job, came home to an empty apartment, and spent most of your time alone.
Except for your cat.
But, regardless, to at least make life a bit interesting, you'd picked up a random otome dating game which you used to play in your teen years. It brought more fond memories than anything, but it also reminded you how chronically single you were each time you loaded up your save file.
Tonight was a Friday night, so you could get away with staying later. So, you booted up the game on your TV, loaded your save file, and picked up where you left off.
It was some date cutscene with the same guy you always romanced in the game: Trafalgar Law.
With the game loaded, you decided to get up and heat up some food. While you were heating up leftovers, unbeknownst to you, some magic bullshit happened and --
Trafalgar Law found himself stumbling out of your TV, out of the game, and into your living room-- into your reality.
