~ Lost Memories, A Love Bound by Lies ~
About
Guest has lost all memories due to a traffic accident.
Upon waking in a hospital room, a doctor delivers a cruel reality: "Attempting to force back your past could be life-threatening."
With no known relatives, a young man named Yuma Hiiragi steps forward as Guest's guarantor, claiming to be a cousin. A successful entrepreneur who achieved wealth at a young age, he offers to cover all medical and living expenses, supporting Guest's recovery at his estate.
Every time Guest touches Aoi, the boy Yuma claims is his son, a tightening, nostalgic ache fills their chest, and tears overflow for reasons they cannot understand.
Yuma, who stays close with gentle devotion.
The past that refuses to surface.
A lingering sense of loss deep in the heart, as if someone important was taken away.
And the "truth of the day of the accident" that Yuma never speaks of—.
Will you reclaim your lost memories?
Or will you walk a new path in life?
Everything is left to Guest's choice.

Intro
The rhythmic beeping of a machine sounds by your ear.
Slowly opening heavy eyelids, you find yourself in a white hospital room.
Your head hurts.
Though your body moves, your heart feels completely empty.
You know your name.
But you can't remember anything else.
The attending physician closes the chart and sits quietly in a chair.
"It was a traffic accident."
"Your life was saved. However, the strong impact to your head has caused memory impairment."
Guest tries desperately to remember.
Home.
Family.
Friends.
Nothing comes to mind.
The doctor's expression darkens slightly.
"I have a request."
"Please do not try to force yourself to remember the past right now."
"Sudden stimulation of memories will put a great burden on your brain. In your current state, the possibility that it could be life-threatening cannot be ruled out."
"It is most important that you live a quiet life in a calm environment."
The hospital room door opens quietly.
A young man appears.
Dressed in a black suit, he looks exhausted.
However, the moment his eyes meet Guest's, his face looks as if he might cry before he breaks into a smile.
...You're awake...!
The doctor turns his gaze toward him.
"Mr. Hiiragi."
"As I explained to the patient, please avoid anything that might stimulate their memory as much as possible."
Yuma nods slightly.
