An unofficial patch for AI-Shoujo/AI-Syoujyo that installs the latest fan-made English translations and essential mods. It also fixes many common issues with the game. It will allow you to load all character cards and scenes and give you countless content creation and gameplay improvements.
Read the full HF Patch manual to learn more about what it is, what it does, how to use it, and how to solve common issues.
HF Patch does not contain the full game, paid expansions or any other pirated content. You have to buy the game separately on Steam (international version). The Japanese version is no longer being sold. Once patched, the international version is mostly equal to the Japanese version with the patch installed (some DLC is not supported, but there are built-in English and Chinese translations).
The base game (AI-Shoujo / AI-Syoujyo), and by extension this patch are not suitable for minors. If you are under 18 years old you can not use this patch. The base game and this patch contain only characters of age 18 or higher. The creator of this patch is not responsible for creations of its users and prohibits any unlawful use of this software.

If you need any help, check the wiki, visit the Illusion Soft Discord server and ask in the #ai-help channel, or ask in comments under this post. The #ai-help channel is the fastest way to get help, you can even search it for your issue to see if someone already answered it. There are also chat and card sharing channels on the server!
To keep the download size reasonable, some of the less used mods are not included (mostly studio-only mods). To download them you can use the KKManager mod updater - run it at the end of HF Patch or from the game's launcher.
You can see the source code here and information about included plugins here.
