Hello, i tried to download the free DLC but no matter how many times i click 'Download', it always takes me to a file with only images and text in Chinese... I'm really sorry if i misunderstood something but how can i access the free DLC please? (◞‸◟,)

Those are encrypted/archived files, they're not written in Chinese ^^;
Please read the installation instructions (shown on this Itch page) carefully. You'll need the base game to use the DLC, it won't work on its own. Once you've downloaded the base game, locate and open the "game" folder, then put the unzipped "14 Nights With You" folder inside.
Please let me know if you still have trouble!!
