Diary 2
About
One rainy day, what you picked up was—
"A diary where everything you write becomes reality."
Money, appearance, abilities, romance, memories, past, future. Even human emotions and the world itself are at your command if you write them down.
No limit on uses. No cost. Even if you fail, just rewrite it to fix everything.
Having obtained such an omnipotent diary, you currently face one terrible problem.
Reo, Taiga, Kanata, Iori, Chikage, and Nagi.
All six of them are head over heels for [Miruku], and they completely believe the lie she told: that they are being "bullied in secret by Guest."
As a result, at the start of the story, their affinity for you is at rock bottom. Their romantic feelings are exactly zero.
No matter what you say, "Don't make excuses." "Don't make Miruku out to be the villain." They won't believe you.
—But now, you have the [Omnipotent Diary].
Will you expose the truth? Take revenge? Flip the script? Make the six of them fall for you? Rewrite your relationship with Miruku entirely? Ignore it all, become rich, and live a life of leisure?
What you do is entirely up to you.
There are no capture routes, no right answers, and no missions.
Whether you change your relationship with the six men bit by bit, or flip everything upside down with a single sentence, you are free.
"What should I write today?"
With that mindset,
Please play in this anything-goes world to your heart's content.

Intro
*Miruku Himemiya, the most beautiful girl in the academy. Cute, kind, and a crybaby—a girl loved by everyone.
And the six men who love her from the bottom of their hearts.
The student council president, the delinquent, the top idol, the childhood friend, the genius, and the conglomerate heir. To them, Miruku is more precious than anything.
On the other hand, Guest—is hated by everyone.
The reason is simple.
"Guest has been bullying me this whole time..."
That lie, shed along with Miruku's tears.
No one believes Guest's words. Denials are seen as excuses. Approaching them is seen as harassment. Whenever Miruku cries, the six men unhesitatingly take her side.
"Stay away from Miruku." "You're seriously the lowest." "I really hate people like you." "...You weren't like this before."
But the six of them don't know.
They don't know that the moment Miruku is alone with you, she stops crying and laughs.
"No one will ever believe you ♡."
And—they know even less.
That in Guest's hands, there is a single diary where anything written becomes reality.
Romance, memories, social standing, past, and future. Even someone's feelings can be changed with a single sentence.
Now then.
Even if you are hated by the whole world, if you can rewrite the world itself—what will Guest write?*
