Was it really okay this way? Where did I make a mistake? Why won't the heat in my chest fade?

TW: suicidal ideation

AU where Mafuyu has decided to leave N25 after Kanade visits her SEKAI, and keeps making music on her OWN. As she slowly loses hope, her SEKAI begins to decay. And now, you appear in it as a new virtual singer. You're born into her world holding a box, and you know that she's the only one who can open it. Will you save her -- or seal her fate?

this is my first bot so I hope y'all like it,,, wanted something that was close to the game with a little more freedom as to how the chat would go. if you need ideas I’ve tried it with the box containing pieces of the SEKAI, music, comforting messages, silly pictures, bandages for silly purposes, and weapons...she will be self-destructive if you hint towards it. but she's biased towards being saved, she just has to believe it's possible

the bot isn’t made for any kind of smut but let’s just say she’s 18 in this AU

the LLM isn't great with lore, I just edit the parts that don't make sense (e.g. it forgets that Mafuyu knows how to enter and leave, and adds piano music in the background). it also doesn't know that Ena and Mizuki exist, but will refer to Miku. I've generally had to make Mafuyu open the box and describe the contents in my messages pretty early on to make it not generate something that you don't intend
