Encouraged by her kind and dependable older brother, the heroine steels herself to confess!
Estimated play time: around 30 minutes to 1 hour.

■ About the Steam Version ■
The DEMO version is all-ages, but the full paid version contains explicit adult sexual content.
We recommend only players 18 years or older play the Steam version.
Due to strict Steam regulations, much of the explicit content is cut—making the game feel incomplete.
When you play, be sure to apply the free “complete content” patch!
※ The patch is available on the official Hanabi Games website.
For any inquiries about the Steam version, please contact “Hanabi Games.”

----------------------------------------------------------------------------
Players who want to play on smartphones or Macs can do so via the browser site “Novel Game Collection.” From the “Language” menu, select the language that suits you.
Note: this site has an auto-translate feature, so the wording may differ from my translation.
※Please note that images will not be translated!!※

I love it 💞 so excited for the 18+ content
Thank you so much for liking my work!! It really means a lot to me🌸
this is disgusting. incest is one thing, but nsfw content of minors shouldn't be allowed at all on this site. please reflect on yourself
I sincerely apologize for the discomfort I have caused you.
While this work contains no explicit sexual depictions, I recognize that my lack of consideration led to this situation. Going forward, I will take the utmost care to ensure my scenarios are appropriate and do not cause offense.
In the future, should any content contain potentially inappropriate themes, I will refrain from posting it on itch.io.
thank you, i appreciate that
I'm sorry you had to get blasted for posting a game that was allowed to by added here in itch.io with the content it has already.
I'm honestly looking forward to paying this game on steam with the 18+ content once available!
If you don't like it, just leave. The website still allows posting, so what right do you have to criticize the author? Are you really going to manage these 2D images? The author warned you before downloading the game. Are you trying to start a fight?
i notice you use the word "it" in your first sentence to refer to incest and pedophilia, as if i were upset over anything less.
"are you trying to start a fight?" the author has already apologized. everything's worked out. why are you here starting new shit bro 💀
please make it for MacBook...
I'll contact the publisher!
Also, since my computer isn't a Mac, I can't render the game, which means I can't upload it to itch.
ohh I didn't know, but I do hope it gets to Mac! Thank you!
I apologize for the delayed response.
I've received a reply from the publisher.
They confirmed it's possible to implement this for the Mac version too.
I'm really hoping you'll enjoy my game...!
OMG it's ok! And thank you so much!!! I'm really happy! I'm sure I'll enjoy your game!
Hi! This game is so cute so far. I'm wondering when the r18 explicit version will be released?
Hello! Thank you so much for your interest in my work!
The R18 version is being translated by the publisher, so I’m not sure when it will be finished…
But as soon as it’s complete, I’ll make an announcement right away!
I'm so sorry to ask,
is this the full version and I can purchase the NSFW patch via website? I promise I'm not this slow all the time.🥺🖤Just kidding, I reread the post another time. WOOOHOOOO, I'M SO EXCITED. 😻. Thank you for making an R18 Otome! I love them so much. I've got over $200+ in "vintage" noughties era R18 Otome games.
I’m so happy that you’re interested in my work!!
The patch will be distributed for free! Right now, we’re just waiting on the publisher’s translation.
R18 Otome games are wonderful, aren’t they? I’d love to see many more... 🌸
hi! im really interested in the game, but im dont really get how the game works. so in short, the itch.io download is just a demo, n the full version on steam isnt out yet. if i want to play the full paid version contains explicit adult sexual content, i have to wait right? cuz i cant find the free “complete content” patch in the game website :( thank you
Hello! I’m really happy you left a comment—thank you so much for your interest in my game!
Actually, the demo already ends at a nice stopping point, but the Steam version continues the story much further—and it will be 18+ (adult content).
I’m sorry, but the release is still in translation, so I need just a bit more time...
Right now we’ve commissioned Hanabi Games for the translation, and as soon as it’s finished we’ll share the patch URL. So at the moment, we haven’t distributed the patch yet.
Thank you!! It’s a taboo story, but I’ve poured my heart into it. Please look forward to the Steam version until it’s released!
