Falling in Love with an NPC in an Online Game

I don't have much to say about myself. If I had to pick something, maybe I'm a genius? After I modified a game designed by some thief, an NPC got clingy with me. And she's an adorable little girl, so what am I supposed to do? NPCs don't come back to life when they die, and she's being hunted, too. So I guess I'm the one who has to protect her.
