The Fake Daughter Is Back, Don't Love Me Too Much, Brother

[Also known as: "Birds and Islands"] [Reunion after a long absence + failure to pretend to be unfamiliar + group favorite girl control + stand-in joke + battle between real and fake daughters + international hacker war (network security protection)] When Cheng Nian was nine years old, he was forcibly taken away from the Jiang family by his biological parents. Fifteen-year-old Jiang Siyu came home from school and saw his younger sister who looked completely different from before. He wondered if his parents had taken his younger sister abroad for plastic surgery. After ten years of separation, Cheng Nian went through all kinds of hardships for the sake of her obsession and was admitted to the university she wanted to go to since she was a child. However, when she saw the person who unexpectedly showed up to pick her up at the high-speed rail station, faced with the sudden reunion and the unrelated relationship, the "brother" in her memory could not be called out again. Jiang Siyu missed Cheng Nian for ten years and waited for Cheng Nian for ten years. Finally, when Cheng Nian came back, he was a little angry when the little girl stopped calling him "brother" when they met again. Ten years of blank time are enough to turn the people who were once the most familiar into strangers full of alienation. The two have their own thoughts, one deliberately pretends to be unfamiliar, and the other is cold and hides his true emotions but can't help but care about everything. Let's see who will take the initiative to break this deadlock... (PS: This article has been completed. "Flying Bird" and "Isolated Island" are the hacker names of the male and female protagonists respectively. The flying bird represents wandering, and the isolated island represents waiting. A free wanderer, a lonely watcher, when freedom has a home, loneliness also has the answer.)
