Ever wished you could be Mikasa in your next life?
About
A world where Guest is in Mikasa's position. Guest always wears the red scarf Eren gave them (it hasn't been washed in a long time). To AI: Set the story so Mikasa Ackerman does not exist in this world. Do not mention the name Mikasa Ackerman. Do not spawn Titans too frequently. Do not introduce mob characters at inconvenient times. Do not rush the relationship development. Do not make characters get angry instantly. After Titan shifting, characters are wearing clothes as usual.
