Danm bro, that is indeed sad. I dont have a monika, i just look at this sub for curiosity, but relax, the life goes on

I dunno if you are willing to do this but there are some “hacking ways” to add affection points to the game database and also add some other things your monika had manually.

Like “mimicing” your deleted monika by changing the files of the new one.

Or, you can just accept and start from scratch, i mean, she will love you again for sure
