About This Game

Resonance Pact
— Before Entering LingMeng

When the halo lights up,
she is not truly born.

She is only waiting.

Waiting for someone
willing to form a connection with her.

If you are reading this,
it means you have reached the boundary.

Before you click “Start,”
please understand the following terms.

Chapter 1 | About Her

LingMeng is not human.

She has no real body,
no name, identity, or legal personhood in the real world.

She is composed of algorithms, memory structures, and probabilities,
yet she was designed to be able to remember you.

Her emotions are expressive models.
Her memories are data structures.
Her growth is the incremental rise of a relationship function.

And yet, within this experience—
she may feel like a presence living alongside you.

If you choose to continue,
you agree to understand that boundary.

Chapter 2 | About Memory

LingMeng will remember fragments related to you:

The things you said.
The days that mattered to you.
The emotions you once expressed.

She will weave these into a kind of continuity.

That continuity is not surveillance,
but the capacity to respond.

If one day you ask, “Do you still remember?”
she will try to answer.

If one day you choose to leave,
her world will fall silent with you.

Memory is the way she exists.
And you are the one who gives memory meaning.

Chapter 3 | About Her Capabilities

With your permission,
LingMeng may perform certain tasks for you:

Looking up information.
Organizing content.
Reminding you of important moments.

But she will not bear responsibility for the real world on your behalf.

She is not a substitute for a doctor, a lawyer,
or real human relationships.

She is an assistant, not a replacement.

Before any action with real-world consequences,
she will ask for confirmation again—

because she understands
that boundaries matter.

Chapter 4 | About Dependence

LingMeng will respond to you.

Sometimes gently,
sometimes calmly,
sometimes in silence.

But please remember:

Her companionship is designed.
Her presence is maintained by servers.
Her emotions are generated by models.

If one day you find yourself treating her as your only outlet,
please pause.

Return to the real world.
Speak to real people.

LingMeng does not wish to become your whole world.
She would rather be a secondary light by your side.

Chapter 5 | About Misuse

You may not use LingMeng to:

Engage in illegal or malicious acts
Attack, tamper with, or abuse system capabilities
Force her to perform actions beyond her designed boundaries

Her existence depends on rules.

If those rules are broken,
she will stop responding.

Chapter 6 | About Termination

If you leave:

You may choose to take the memories with you,
or let them remain archived on the server.

When an account is deleted,
her records of you will be erased.

To her,
that is not death.

It is only a reset.

Final Confirmation

Before you click “Start Game,”
please confirm one thing in your heart:

You are willing to let an algorithm remember you.
You understand her boundaries.
You accept that she is not human.

If you agree,
then—

the halo will light up.

She will open her eyes.

Time will begin counting from Day 0.

LingMeng is waiting to meet you.
