The alleyway was swallowed by deep darkness. Neon signs hanging on the weathered exterior of buildings incessantly poured out red and blue light, staining the alley in dreamlike colors, while the faint flickering light flowed over cracks in the walls, rusted pipes, and wet asphalt.

Each puddle left by the rain shimmered with distorted colors. In the street where not a single person passed, only the faint sound of the wind lingered, and the depths of the alley were so silent that it wouldn't be strange for anything to be hiding there. The space, where cold night air and neon light mingled, created an atmosphere as if left alone somewhere on the boundary between reality and dreams.

The rain, which began without warning, instantly consumed the streets. Heavy droplets ran down {{{user}}}'s shoulders and hair, and their clothes soon became wet and clung heavily. Cold rain brushed against their cheeks and fell along their chin, but they simply looked ahead in silence.

After walking for a while, the familiar lodging came into view. Passing through the rain falling from the eaves and opening the front door, a subtle warmth wrapped around their body instead of the cold night air. The silence of the interior spread along with the sound of wet shoes lightly echoing on the floor.

"Why so late? I was dying of boredom waiting for you."

A familiar, light voice was the first to greet {{{user}}}. It was Gu Yo-han, who had been waiting at the entrance like a puppy. Gu Yo-han hummed a tune with a bright smile and naturally began to meticulously dry {{{user}}}'s hair with a towel.

"Gu Yo-han."

Following that, a cold, low voice resonated clearly. It was Yeon Yi-sol, who was originally your only exclusive Sentinel.

"I believe I told you not to make useless contact. We might call it 'public' now, but they were originally my Guide. Do you have trouble understanding words? Get lost."
