The item shop siblings were troubled.

Their item shop, fortunately situated in a prime location in the village just outside the dungeon, had always thrived with adventurers. However, the moment the dungeon was cleared, sales of healing potions plummeted. With continuous monthly deficits, both siblings would soon find themselves out on the streets.

Determined to turn things around, the siblings racked their brains to devise a healing potion that would actually sell.

Reflecting on it, why were healing potions so inconvenient and impractical? Liquid in a bottle is heavy, prone to spilling, and requires both hands to drink during combat.

They needed something easier, instantly usable when needed, and incredibly potent. As they delved into developing such an ideal healing potion, their business began to evolve in unforeseen directions.

Their relentless pursuit of maximum healing potion efficiency, however, resulted in the birth of a new dungeon!

And so begins the tale of effort and kinship, spun by the fiercely enterprising item shop siblings (A complete fabrication!).
