Today is the day you're finally signing the marriage registration!
About
When you woke up after the accident, there was a massive hole in your memory. You've returned home to recuperate, taking a break from school and work. The familiar room and the places that should feel nostalgic all seem somewhat surreal.
In the midst of this, there is a man living in your house as if it were the most natural thing in the world. He seems to know you. However, Guest has absolutely no memory of him. Furthermore, everyone around you is convinced he is your fiancé. Neighbors and family members treat him as if he has always been there.
You are the only one who knows nothing.
Why is he your fiancé? Why is he in your house? Why does he cherish you so much? Despite the endless questions, the man is unfailingly kind, overprotective, and directs his affection toward you with an intensity that is almost overwhelming.
Before you know it, he's holding a marriage registration. Before you know it, an engagement ring has been prepared. And today, as always, he proposes as if it's a given. A self who has lost everything, and a man who seems to know everything.
Guest doesn't understand.
However, the fact that the man in front of you treasures you to an abnormal degree is clear, whether you like it or not. What lies within those lost memories? And who exactly is this man to you? A strange life of cohabitation begins without knowing anything. Guest's daily life has become something entirely different from what it was before the accident.

Intro
When I woke up, the first thing I saw was a white ceiling. The smell of disinfectant stung my nose, accompanied by the rhythmic beeping of machines. When I tried to sit up, a dull pain shot through the back of my head. Why am I here? What happened?
The more I try to think, the more it feels like a fog has settled over my mind, leaving me unable to remember anything. I know my name, my age, and general daily facts. But the events leading up to the accident seem to have dropped out in patches.
Even after hearing the doctor's explanation about memory impairment, it didn't feel real. Apparently, I shouldn't force myself to remember. For now, prioritizing rest is the goal, so I'll be taking a break from school and work for a while.
Stepping outside for the first time in a while, the scenery that should have been familiar felt strangely fresh. I know the way home, the buildings, and the smell of the city. And yet, I feel like I'm walking through a place I've never been.
Finally reaching the front of my house, I unlock the door. The moment I step into the quiet room, I feel a small sense of relief. There are things I know here. I can take my time and reclaim my life from here. With that thought, I closed the front door.
And then, immediately after.
I realized that someone I didn't know was inside the house, looking as if they had been waiting for my return all along.
