(Important) We've discovered that some people on the web have been decompiling and interpreting the code directly. As a result, we've added security measures and anti-cheat code. Due to this, when running version 1.1.0, if you have existing data, a warning message may appear and your data might be reset. Before launching the game, we recommend pressing Windows+R, typing %APPDATA%, navigating to the yankee_massage folder, and deleting the Local Storage folder. If this is inconvenient, you can run the game once with the sound off (it might be a bit noisy), then restart for normal gameplay.
Hello, this is Walumiyo.
We've finally completed version 1.1.
Initially, our plan for the v1.1 update included improving animation details, adding animations that reflect actions in the other two cuts when performing actions in the central cutscene (showing genitals and breasts), and implementing items. However, based on your feedback, we've changed the direction of the update.
Here are the modifications: 
Additionally, we decided to provide direct download links here for our Patreon supporters from now on! Since one patron's support generates more revenue than a single game sale on DLsite, we'll make downloads available starting from the Onigiri tier.
The download link is as follows, with the password: loveWRMY

([JST 20:57 updated] The above is the download link for version 1.1.2, which fixes the bug that occurs when wearing sexy underwear, entering week 10)
Thank you for your patience!
As we're just two people handling all the work, there are likely still areas that need improvement. We've done extensive testing for this update, especially for debugging, but it's challenging to cover every scenario in a short time. We appreciate your understanding if we haven't eliminated 100% of the bugs.
We're truly grateful for the warm, encouraging comments left on the 1.0.4 update post. Your support motivated us to keep working hard.
Our next project will be another short-term one, planned for release in August or September.
Originally, we planned to create a game themed around a women's hospital (with the protagonist qualified in general medicine, proctology, and gynecology). However, since some of you have expressed interest in additional massage game content, we're considering making a second massage game featuring about four new heroines.
Thanks to your love for the game, we've earned enough to cover our living expenses for a few months. This means we won't have a 30-day time limit for the next project, allowing us to focus on thorough debugging and a less stressful development process.
We're truly thankful that you've enjoyed our game despite its shortcomings. We'll take about a week off, then return with news about our plans for the new project.
Thank you so much!
