One night, Arin stands in front of a mirror, combing his hair

Description

A vibrant, colorful 3D animated series featuring humanoid characters, with smooth animation, a mysterious fantasy-adventure atmosphere, and cinematic lighting. Set in a small village in Bangladesh, the story follows Arin, a 16-year-old boy whose parents have no idea that he possesses a strange supernatural ability: every night at exactly midnight, his shadow moves of its own free will. One night, Arin stands in front of a mirror, combing his hair. Suddenly, he notices that his reflection in the mirror remains completely still while his shadow on the wall moves independently, reaching out with its hand to write something. Frightened, Arin steps backward as three words slowly appear on the wall: "তোমার বাবা বেঁচে আছে।" (Bengali dialogue: "Your father is alive.") Arin's father disappeared ten years ago, and everyone believes he will never return. Trembling, Arin asks in Bengali, "তুমি কে?" ("Who are you?"). His shadow replies in Bengali, "আমি তোর সেই অংশ, যাকে তুই কোনো দিন চিনিসনি।" ("I am the part of you that you have never known.") Suddenly, the room's light goes out. In the darkness, the shadow speaks again in Bengali: "কাল রাতের আগে পুরোনো রেলস্টেশনে যা। কিন্তু মনে রাখিস, সেখানে যদি নিজের মুখ দেখতে পাস, তাহলে পালাবি না!" ("Go to the old railway station before tomorrow night. But remember, if you see your own face there, don't run away!") The next night, Arin arrives at the abandoned railway station, where no trains have run for almost twenty years. Exactly at midnight, the distant sound of a train echoes through the darkness. An old train approaches and stops at the platform. Its doors open by themselves, revealing a man sitting inside. The man's face is an exact match for Arin's, but he appears to be around forty years old. Sitting beside the window, the mysterious man looks at Arin and says in Bengali, "এত দেরি করলি কেন, বাবা?" ("Why are you so late, son?") Arin stares at him in astonishment. The older man holds a photograph of Arin that was taken exactly ten years in the future. As the train doors begin to close, Arin steps inside. The train disappears into the darkness, leaving the abandoned station empty. The next morning, the villagers discover only one thing at the station: Arin's shadow. Arin himself is nowhere to be found.
