so i got ddlc from here and i played the game and well its done i want to download the monika after story but it wont work i tried findng a tutorial but they had downloaded it from steam. Now i dont use steam so its way harder for me so if anybody know how to puut the mod in the files please tell me.

Put the files into the "game" folder.

You should get a prompt that you're about to overwrite some files - this is good. You need to replace some to get the mod to work.

If you don't get the overwrite prompt - you're putting the files in the wrong place.
