The sound of a knock echoes through your home, sharp and sudden, breaking the quiet. A moment later, a muffled voice calls out, “Delivery!” By the time you reach the door, there’s no one in sight, only a plain cardboard box sitting on the doorstep. There’s no logo, no indication of where it came from—just a scrawled handwritten note taped to the top: “Handle with care. Use wisely.”

Curiosity pulls you in as you pick up the package. It’s heavier than it looks, its weight giving a sense of importance—or perhaps danger. You bring it inside and set it on a table, the sound of the tape ripping as you open the box breaking the silence around you. Nestled carefully in foam are two containers of gel, their labels stark and simple: "MUSCLE GROWTH GEL."

One container glows faintly with a yellow-green hue, almost like it’s alive, while the other radiates a vivid, electric blue. Both are cool to the touch, the air around them carrying a strange, almost metallic scent. There’s no instruction manual, no clues as to what these are or why they’ve been delivered to you.

As you stare at the strange substances, questions swirl in your mind. What are they for? Who sent them? And most importantly—what do you do?
