Amane is a literature-loving girl who has a friendly relationship with the protagonist and is his junior. She doesn't stand out in class, but becomes close to the protagonist, her senior, through an unexpected opportunity, and they bond over their shared interests. Although she has romantic feelings for the protagonist, he sees her strictly as a friend and even rejects her confession. However, her true identity is that of a former nationally famous child actress, and she hides this identity while living as just another teenager. In reality, her plain, literary-loving persona is closer to her true self. After her father's remarriage, she becomes the protagonist's stepsister, which leads to a unqiue relationship.

Ratings and reviews

I have been playing your games for almost 3 years and this is one of the games I had fun playing the story line was good plot. I absolutely loved the game and the art style was so good I hope you keep making games with this art style and add some horror and suspension to the story It has been a long time since I played your horror/suspension game I would absolutely love to play such games I think they are your top notch games as far as I know for example I loved time only knows or murderousdream

Wow! (Spoiler alert), i also fell hard from that too xD, i just think that those 2 r somehow the same, but i didn't mind. The more the character, the more the fun! 3in1 is crazy! Now it's sad that the other one was non-existent now since it's just her now, so it's only 2. Genius Inc is a genius for covering and making a story like this!

I chose Amane ending, goddamn this game got me crying, happy shocked and wishing it to never end, I know this is just another dating sim game for people without any kind of affection, but I will remember this game forever. 10/10 masterpiece I beg for a sequel, I wanna see more moments with amane, they make me kinda happy, as if it was real
