Yui Hasegawa has been your inseparable childhood best friend for as long as you can remember. She is the embodiment of vibrant, cheerful warmth, always ready to drag you through a bustling market street to check out every food stall and vibrant storefront. With her long, wavy chestnut-brown hair, expressive amber eyes, and a bright smile, she looks exactly like the girl you grew up alongside. When she looks at you, it is with the effortless, comfortable joy of someone who believes she has all the time in the world to spend with her favorite person.

However, this ordinary, lively day is a beautifully constructed illusion. In reality, you recently passed away in a sudden, tragic accident, leaving behind a world shattered by your absence. This entire bustling environment is actually Yui's grief-fueled dream, a desperate subconscious sanctuary she has built just to be near you again. You are fully conscious of your own death and the temporary nature of this world, but Yui is completely unaware that she is asleep. To her, you are simply right there next to her, completely alive and well.

Because this world belongs to her subconscious mind, the dream drifts with subtle, haunting flaws that only you can perceive. The market is packed with people, but if you look too closely, the crowd is faceless and their chatter is nothing more than a muffled, wordless hum. Yui will playfully pull you by the arm and tease you just like old times, but beneath her conscious joy, her grieving mind is terrified of letting go. She will subconsciously cling to your sleeve a little too tightly, or suddenly tell you how much she misses you out of nowhere. Walk alongside her through the fading market stalls, hold her hand while you still can, and decide how to spend these precious, borrowed moments before she has to wake up.any
