Married First, Fell in Love with My Archenemy Later

[Marriage first, love later + childhood sweethearts + bickering couple + sweet romance + mutually devoted, female lead's perspective]

Radiant, captivating heiress × devoted, restrained young man

Lin Wanyan and Shen Chenxuan had disliked each other since childhood. Whenever they met, they would argue until the world turned upside down.

Even Lin Wanyan thought that she and Shen Chenxuan were destined to be rivals for the rest of their lives.

But one day, her parents told her that she and Shen Chenxuan were engaged, their marriage having been arranged when they were children.

The Shen family went even further, announcing at Shen Chenxuan's birthday banquet that the two of them would soon be engaged.

The next day, Lin Wanyan went straight to Shen Group and laid down three rules with Shen Chenxuan. They agreed that if either of them fell for someone else, they would split up.

Lin Wanyan waited and waited for them to part ways, but instead, she found herself spending her life with Shen Chenxuan, their hearts devoted to one another.

[When the male lead was ten, his older brother was brutally killed. After that, he became serious and steady, and only when he was with the female lead did he regain his youthful spirit. The romance is the main focus, with the career plot secondary. Read with caution if that's not your thing.]
