How Did the Heroine and the Villainess Get Their Happy Ending?

Ye Nianzhen suddenly awakened to the truth of her world and realized in shock that she was the vicious female supporting character destined to die a tragic death in a book. The heroine was Jiang Zhiyu, who had transmigrated into a book.

According to the story, Ye Nianzhen was the fake heiress who had been switched at birth and had grown up as childhood friends with the male lead. Jiang Zhiyu, meanwhile, was the real heiress. The two would fight tooth and nail over the male lead, and Ye Nianzhen would be trampled under Jiang Zhiyu's feet for the sake of this man, disgraced and ruined.

Ye Nianzhen snapped back to her senses and looked up to see Jiang Zhiyu coming to find the male lead after class. Jiang Zhiyu hadn't yet been reunited with her birth family, and wore a timid, pitiful expression. Ye Nianzhen's heart tightened as she remembered all the cruel, foolish things she would later do. It was so absurd she could barely bear to think about it.

…

After Jiang Zhiyu transmigrated into the book, Ye Nianzhen's thoughtful gaze was always on her. Bored, Jiang Zhiyu looked away, thinking Ye Nianzhen was probably coming up with another way to frame her.

She pushed open the door without a second thought. Just as she expected, there was a prank waiting for her, but in the next moment, a sudden force wrapped around her and held her tight. Jiang Zhiyu opened her eyes in shock and saw Ye Nianzhen's striking face. The other girl had her eyes shut, drenched from head to toe, holding Jiang Zhiyu firmly in her arms.

Jiang Zhiyu initially thought it was just an accident, but the plot kept veering further off course. The love letter the male lead gave her was mysteriously thrown away;

On her birthday, the female supporting character showed up with a cold expression and stiffly tossed out a "Happy birthday";

Even more alarming, Jiang Xianyu discovered that Ye Nianzhen had set her photo as her phone wallpaper.

Jiang Zhiyu's mind exploded with a buzz: What kind of main-character treatment is this? How far has the plot gone off the rails?!

…

The male lead found Ye Nianzhen more and more irritating. His childhood friend treated him as coldly as a stranger now. But she was only a fake heiress, so what gave her the right to give him the cold shoulder?

Until one day, he accidentally stumbled upon

Jiang Zhiyu leaned in close to Ye Nianzhen and pressed her: "Ye Nianzhen, do you... like me?"

The male lead froze on the spot, eyes wide with shock: What earth-shattering secret have I just stumbled upon?
