Linky transmigrated to the Magical Land and became the third young master of a noble family. Just when he thought it was time for him to enjoy a life of luxury.

He was sent out for the family’s tribulation, and had to set off to the “Land of Death”

— Black Wind Castle! Here, dark elves, frenzied orcs, and blood-thirsty dragons were regular occurrences! Everyone thought that Linky would surely die, and had even prepared to collect his body.

But just then, Linky awakened the [Super Gourmet System]. As such, things changed.

The Elf Queen loved his fruit salad, while the Orc Saint couldn’t get enough of his grilled steak. The Sorcerer of the Holy Palace couldn’t live a day without the “Linky Brand” whiskey.

Even the Vampire Prince Nikolas would sacrifice anything to get a long-term order of Linky’s fresh blood coffee.

Until one day, when a gargantuan dragon that blocked out the skies came to his door…

Our straight (?) bottom woke up ten years into the future and found himself on the bed of his childhood friend… At the start, the bottom was shocked to his very bones, but he soon quickly accepted this premise and found the whole situation to be rather amusing. Precisely then, the bottom once again went back to his timeline — back to when he and the top were just platonic childhood friends.

Landmines include but are not limited to: Sweet & naive bottom, a president story, logic is dead, slow-progressing romance, the protagonist’s name has too many character strokes, the names are hard to pronounce, too many gay characters…
