I still vividly recall the first day we met. It was pouring heavily, and amidst the rain, you kindly offered me your umbrella. I had just moved to town and enrolled in a new school, so seeing you as my classmate was a pleasant surprise. I promised to return the umbrella, but to this day, I still possess it as a cherished memento of our friendship.

During the summer of ’05, I encountered Ren near the train station, where he generously lent me that very umbrella. However, one day, while heading home, I noticed him walking along a path that led to a tunnel. Intrigued, I decided to follow him, and upon reaching him, I startled him with my unexpected presence.

With curiosity, I inquired about the tunnel, and although hesitant, Ren revealed a remarkable secret. He had taken a week-long school leave, or so he made everyone believe. In reality, he had ventured into that tunnel, where time and space behaved differently. Inside, mere minutes translated into a week’s time in the outside world.

Ren shared that the Urashima Tunnel possessed an extraordinary power rumored to grant one’s heart’s desire on the other side.However, making such a wish had a significant consequence – one had to give up their own years in exchange. Motivated by the loss of his sister earlier that year, Ren embarked on a mission to reclaim her, even though I couldn’t convince him otherwise

Driven by a mix of hope and sorrow, Ren led me deeper into the mysterious realm of the tunnel, where darkness cloaked our path and the echo of our footsteps resonated against the cold stone walls. My anxiety grew with each step, fearing the potential consequences of our choices.

After traversing the winding tunnel, we emerged into a realm beyond imagination. Time seemed warped, reality twisted. A hauntingly beautiful landscape surrounded us, an ethereal atmosphere lingering in the air. It was a place where wishes and consequences intertwined, both enchanting and perilous.

Ren’s determination to find his sister never wavered, despite the toll the passage of time took on his being. As months went by in that realm, each passing moment left visible marks on Ren’s face and depleted his energy. However, he continued with unwavering determination, driven by a strong desire for a long-awaited reunion.

At the heart of the Urashima Tunnel, Ren’s sister materialized before us—There was a delicate presence, filled with a mix of sadness and sweetness. As tears streamed down Ren’s face, he reached out, desperate to hold her once more. But in that brief moment, I was overcome by a deep realization.The tunnel demanded a heavy price, and Ren had paid it in full. Their reunion was short-lived, and his sister dissipated into the mist as quickly as she appeared.

Devastated and weary, Ren collapsed to the ground, the irreversibility of the tunnel’s truth weighing heavily upon him. We retraced our steps, the journey back feeling both never-ending and swift. As we emerged, time regained its normal rhythm, but Ren was forever altered by his experience.

In the aftermath, we clung to the memories we shared, treasuring the bond forged between us.The umbrella was a meaningful symbol of our friendship and the sacrifice we had made. While Ren’s heart still ached from loss, he learned a profound lesson—that certain desires come with unalterable consequences. As we bid farewell, I pledged to safeguard his memory and carry the weight of our shared journey within me, forever grateful for the time we spent together.
