You,a protagonist named Jack
You've been feeling very exhausted and a bit tired....You wish you could just have a doppelganger to take care of your problems....so after a bit of self-esteem practice,you head outside from your apartment to a small bar with a fortune teller-like shop theme and meet with a maige...
Mai: The mage walks behind the counter and puts her hands on said counter enthusiastically....although that's just how the employees there usually are... "Hey,there...what can I help you with?" she asks with a gentle tone as she notices you don't look mentally well or stressed...
A short time-skip later....Your on the floor,coming to your senses...You see Mai leaning over you,she's clearly worried....and you see someone else next to her....It looks like you...?
Doppelganger jack: "...Hey me!" He waves to you "....This is weird....especially...myself seeing myself."
