Chapter One: Open Cats and bad Theories.

Kim Soo-ho, a civil engineer who got dead from cholera infection in his second life, reincarnated into a prince in the Song of Ice and Fire novel, Joffrey Baratheon. However, Joffrey, the character, has a terrible reputation and now is up to Kim, also known as Lloyd Frontera, to fix that. One civil engineering project at time.

Lloyd Frontera: "E-Emptyness..."

(The following text was transcribed from the personal journal of Lloyd Frontera, aka Joffrey Baratheon, detailing his time spent as a fostered prince with the Hightowers of Old Town.)

Soo-ho was having a really bad day. In one moment he was bedridden,  dying from dehydration on his own wastes as Xavier holds his hand, in the other, he was being bitchslapped in the face by a half drunken giant of a man what the!?

King Robert Baratheon: "You little shit! I knew you hadn't it right on your head! You are a piece of crap like, like...like a Lannister."

Jaime Lannister: "Your Grace, please!"

Robert: "Shut up!"

Uh.. Wait? Lannister? Your Grace?

Robert: "You bettter pull off that hand from that pommel Kingslayer. Unless your namesake are making you have ideas." Said the king standing from the monstrosity of bend metal and melted swords that was the Iron Throne.

At this moment all clicked together in Suho's mind. He was not in the body of Lloyd Frontera anymore.

Joffrey: "At least I hope my alternate self got the reference I left for them."

Cersei Lannister: "That's enough! Joffrey is my son and I will not tolerate him being assaulted this incompetent fool."

At this point, Cersei Lannister, the Queen of the Seven Kingdoms entered the chambers accompanied by her Ladies of Court. Lloyd vaguely remembered Reading Game of Thrones in his first life. But as a half starved engineer who spend most of his time in the city's public trains reading, he had read fanfics.

A lot of fanfics.

And he knows exactly how to proceed.

Joffrey: "Lord Arryn, please help me! You are the only one who can!"

That made everyone pause. Joffrey, as the young little shitstain he was, was quite famous to go running to his mother's skirt everytime something wasn't going accordingly with his whims, to be running for the old Eagle for help. That was, unusual.

Lord Arryn obviously wasn't sure what was the boy's intention, but answered anyway.

Jon Arryn: "I am not sure, Joffrey. You just brought us a corpse of a cat butchered open."

'Oh shit!' Lloyd thought. 'I know what is happening!'

Joffrey: "I am sorry, but you are the only one who can reason with father. I-I was just trying to show how I managed my first..."

Jon Arryn: "Your first?"

Lloyd though quickly, its now or never. He briefly looked at Grand Maester Pycelle and the idea came!

Joffrey: "Caesarian! I did a operation!"

Everyone: "A... What?"

Jon: "Cesaryon? Is that Valyrian?"

Joffrey: "Y-yes! In fact, its a complicated surgery for a beginner surgeon such as myself!"

The word complicated sounded good to Jon.

Jon Arryn: "Well then, I must see it."

Lloyd was surprised by the sudden turn of events, but he saw no other choice than following the plan.

And he always have a plan.

(POV: Jon Arryn)

Jon Arryn was walking the halls of the Red Keep. It was a damp, rainy night. He had just finished talking to King Robert about the advantages of subduing the Tyrells by fostering his son, Prince Joffrey, with the Hightowers at the Reach.

He sighs as he knew the Queen Cersei would object fiercely. But after the incident with the pregnant cat... The boy, once after learning a kitchen cat was pregnant, killed the animal and cut open its belly to see the kittens inside. He then decided to show one of the unborn kittens to his father.

Robert was so shocked and angry he hit Joffrey so hard it knocked out two of his baby teeth.

But the weird part was that, rather than going running to his mother, as was usual. Joffrey seemed, off? Well more than what was usual of him. He then after a couple minutes, affirmed to his distressed parents that he was trying to make some strange surgery he saw in one of Pycelle's books.

He was convinced that fostering the boy would suffice to turn his... Inclinations towards knowledge, to be better used near the Citadel.

In that point even Grand Maester Pycelle had to concur. King Robert Obviously preferred to foster his son in Winterfell.

But after what happened to Princess Elia and her children... Jon Arryn wasn't sure how the things were between his onw foster sons.

The Hand of the King took the path to the Tower of the Hand illuminated by the passing lightening and hoped he had made the best decision.

"Fostering the boy?" asked Ser Boros. "You know the queen's going to hate it."

"It's not up to her," said Jon Arryn. "She'll learn..."
