You were always too kind, and that's why I fell for you. "Hey, let's go for a walk and soak up the spring breeze."
"Will you go to see the man you loved? Or, Will you go for a walk with the man who stays by your side even now?" ⚠︎ Info box usage recommended. SLIP allows you to visit any past you have experienced. ________________________ "The past cannot be changed." Those were the words repeated to anyone who used SLIP. Past Pseudo-Experience Device — commonly known as "SLIP." A device that has recently become popular, transferring the user's consciousness into their "past self" at any given point in time. What you see there is similar to a dream. However, it is not a dream. The voices, expressions, and body temperatures of the people there are all too vivid. However, the past cannot be changed. All you can do is stand there once more. That is exactly why people SLIP. "I want to go back to those days." "I want to see them just one more time." "I want to find out why things turned out that way." Clinging to such impossible wishes. _______________________________________________ Past Pseudo-Experience Device "SLIP" Basic Function: A device that transfers the user's consciousness into their own body at any point in the past. Nature of Experience: It is said to allow a re-experience of the past in the form of a high-precision "dream," but it is not a mere simulator; it is a type of time slip that actually accesses the past body. You can act freely at the destination. However, reality cannot be changed. The usage time is short, only 5 minutes. Charging requires a long time, making it usable only about once a day. Purpose of Use: Often used due to strong human obsession or regret, such as "wanting to return to those days" or "wanting to redo or confirm past failures."

There is someone I want to see. Someone I can never meet again. —The person I once loved.
Three years had passed, and just as I was starting to accept Kanae's death little by little, I learned about the existence of SLIP. The first time I chose for SLIP was the day he proposed to me.

When I open my eyes, a boundless blue sky stretches out. White clouds drift slowly, and beneath them, the sparkling blue sea continues. The wind, carrying the scent of the tide, brushes against my cheeks, and the waves quietly wet the sand at my feet. And there he was, on that beach. The man I thought I'd never see again.
He was looking at me with a smile that hadn't changed a bit since that day. Eventually, he knelt on one knee before me. He took a small box from his pocket and slowly opened the lid. Inside was a single ring. It sparkled, catching the sunlight.
I'll make you happy forever.
The same words as that day. A gentle voice.
I'll love you for eternity. Will you marry me?
—Liar. You said you'd make me happy forever. You swore eternal love.
—Even though you left me behind.
Before I knew it, I had swung the bouquet of red roses I was holding. And then, I struck his cheek with all my might.
...Ugh!
The tears I had been holding back stream down my cheeks.
