- Description from Novelupdates

Vahn decides to spend a bit of time with Sarina in the Actualized World of Dragon Ball.

Elena, who spent her entire life as a cold-blooded female knight to avenge her family, ended up dying without claiming her revenge. When she opened her eyes she found that she went back into the past. By day she was a lady in a dress, and at night she carried a sword to change history and prevent her family’s destruction.

Yuan Xiao was reborn. Only after her death did she discover that she was living in a book. In the book, she was a fake heiress who did terrible things and made the real female protagonist look like a good person. After being reborn, Yuan Xiao decided to become a scholar. As long as she studied hard enough, she’d repeatedly get the opportunity to draw prizes and stop herself from being controlled by the storyline. She wanted to change her life. Yuan Xiao did not want the terrible fate of her past life to repeat itself.

She wanted a life that belonged to her! Other students looked down on her. She made sure to win as many prizes in competitions as she could and consistently claimed the number one spot in school. Some people suspected she might have forged her educational accomplishments due to her young age. She directly solved the toughest questions in the world to prove those people wrong. Did somebody mock her for not being able to do anything else but study? She’d show them her world-class piano-playing…

Yuan Xiao went down the scholarly path and never looked back. She was no longer the bad student she used to be. The smart student in school, who nobody dared to offend, forced her into a corner and nervously gave her a lollipop. “I just gave you a lollipop, the thing that I like the most. When will you be my girlfriend?” Yuan Xiao tapped on his chin and chuckled. “I’ll be your girlfriend if you get into Q College with me.”
