Nice to meet you, I'm Japanese.
I am sending this message from Japan. I'm using Google's translation function, so please forgive me if there are some strange parts in the sentences.
About a year ago, I bought Heart of the Woods on Steam. It's a great game and I really enjoyed it.
But there is one problem. 
I was told that there is a R-18 patch for this game, but there is no patch on the Steam official site, and I tried to get it from Denpasoft, but I couldn't. 
I couldn't access the site from Japan.
I tried everything, but I couldn't get the patch for Steam.
It's been about a year since I bought it, but I still really want to get the patch.
Would it be possible for you to take measures such as providing or selling patches, such as distributing them on Steam? 
I know it's selfish, but I really want to get the patch...
I couldn't think of any other way to consult, so I took this form. Excuse me for the long message. Thank you.
