Good Evening, Mr President! - Chapter 1892 - : Public display of affection

In a world of countless enemies, the right talent is all it takes to thrive. Freddy Stern, a twenty-one-year-old cashier, has lived a plain, albeit harsh life. Having been orphaned—twice—he’s spent the last ten years working and staying out of trouble. His only aspiration is to save enough money to become an archhuman. His dream gets the jump on him when he barely survives a near-death encounter and finds himself with 1% Lifesteal, a bizarre talent with numerous contradictions and just as many uses. With every dead enemy, he becomes a bit stronger, a little wiser, and a lot more ruthless. And no matter how much damage he takes, he can always put himself back together. Physically, at least. But on his path to power, after having to look at the rotting guts of archhuman society again and again, can his talent keep his mind and soul as pristine as his body? Or will that part of him simply remain broken?

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory? Or will he succumb into a conspiracy lurking within the country's borders?

And then somehow, I became a bigshot.

The MC entered the body of the An family eldest son, An Ziran, an arrogant 16 years old boy who weighed 78 kg (~171-172 lbs), who only knew how to eat, play and sleep. Seeing his current body, An Ziran decided his first priority was to LOSE WEIGHT!
