[Prince of Tennis] Beyond My Childhood

[Book Blurb]: When Yuejian Ximiao woke up, she discovered that she was in Yagyu Hiroshi's room. Even more shocking... The calendar on the bedside table said it was four years later. She suspected she had transmigrated into her future self. Looking down at her chest, she saw a pretty curve beneath her thin pajamas. At a glance, she was a B cup. So Yuejian Ximiao opened the bedside table drawer and found an ID card in her wallet, issued when she was sixteen. Then she rummaged through a box and found... A marriage certificate for Yagyu Hiroshi and Yuejian Ximiao, with one copy for each spouse. Yagyu pushed up his glasses and explained, “About what you said... that you don't remember these past four years, I spent all morning looking through the records.” Sitting on the bed, Ximiao glanced from afar at the medical literature database on the webpage and asked curiously, “What did you conclude?” “Nothing so far.” Yagyu seemed quite serious. “If I had to guess, your hippocampus has atrophied?” Note: The hippocampus is the part of the brain responsible for memory. [Author's Note]: The female lead has not transmigrated; she's a local. The setting is a university campus, and the story is a literary romance. The male lead is set as Yagyu. No character corruption, no following the original plot, and a happy ending. The overall tone is warm and cozy. I hope to portray the proud and loving Yagyu as I imagine him. Theme:
