LOL: I am a bad prince in Demacia

Lucci traveled through time, and when he opened his eyes, he came to the world of League of Legends, Runeterra - Valoran!
At the beginning, the family was destitute and there was an old mother who was seriously ill in bed. It was a nightmare start.
However, before her death, her old mother gave him a mysterious necklace.
When he arrived at the royal capital of Demacia with the necklace, he suddenly discovered that his father, whom he had never met, was actually the current king!
In a blink of an eye, Luqi became the second prince of Demacia. His elder brother was Jarvan IV, and his uncle was Xin Zhao, the German steward.
With such a background, Lu Qi suddenly felt that there was nothing wrong with him being a spoiled prince.
By the way, he also awakened a sign-in system.
It seems like a pretty good life to just sign in and tease the blond girl from the Mianwei family next door and flirt with the neighbor's Miss Sword Girl.
