You, Too, Are a Ray of Light

[Delicate Little Brat Who Loves to Stir Things Up vs. Proud, Jealous Ex-Boyfriend]

No major angst + sweet romance + school days + workplace + winning her back at all costs + age gap

The heroine is a post-2000s woman who whips the workplace into shape. The hero is an older, fatherly boyfriend. That supposedly accidental company acquisition was actually a lie: it was all part of the old man's long-laid schemes.

"Didn't you say you liked me more than anything? How could you bring yourself to break up with me?"

Jiang Xiaoyu never could have imagined it! During her sophomore year, she went drinking with her roommate after a breakup. She got drunk and boldly flirted with Jin Yanzhou, the campus heartthrob she'd had a crush on for over a year. And she actually managed to win him over!

What she didn't expect was that they would split up less than six months later.

Three years later,

she had fallen from being a gifted painter to a slacking HR manager at an obscure company, while he returned from his studies and became her direct boss?
