Ethan is a man nearing forty who has squandered his life behind a screen. Since his teenage years, he has poured everything into online games, chasing digital achievements while real life quietly passed him by. Now, with reality finally weighing on him, he realizes how empty his existence has become.Despite decades of obsession, he has only one thing to show for it: the #1 account in the world’s most popular MMORPG, Lost World Online—a fully immersive virtual game operated through neural-link technology. It is an account powerful enough to guarantee fame, sponsorships, and a second chance at life.But overnight… it vanishes.No warnings… No errors… His account simply ceases to exist.Ethan spends the entire night frantically searching for answers, contacting the developers through official forums, only to be told that nothing can be done. Without the account, even streaming or professional contracts are impossible. Exhausted and hollow, he finally gives up and falls asleep, deciding to forget his regret, half hoping everything would be a dream when he wakes up.When Ethan opens his eyes, he finds himself standing before the character creation screen of Lost World Online.It feels like a dream, yet his mind is clear, his body well responsive, not even like a game. Paying little attention, he goes ahead and creates a character and initiates the game.Then, his vision is swallowed by darkness.A violent rush of wind slams into him, and when his senses return, he is standing inside a bustling town from the game. Before he can question the missing opening cutscene—something that should always play after character creation—his attention is seized by the scene around him.The town was celebrating an Annual Festival. This was a festival that only ever occurred once, a festival that marked the first day Lost World Online was launched.Realizing the impossible, Ethan hurriedly calls up his system interface—only to find that there is no options menu, no settings, no log-out button…“This cannot be real.”

“But he is a good man,” she argued to see his eyes narrow at her words.

Twenty years ago, she was taken in as the Lin family’s young heiress through a twist of fate. But mistakes would eventually be corrected one day. When the real daughter of the family returned and her foster parents begged her to stay, she obliged. Unbeknownst to her, this was actually a scheme disguised as familial affection. They only kept her around to squeeze her dry of all her value!
