Both leads have only been with each other + rekindled romance + a physical relationship
[Clear-headed good girl who is emotionally tangled and starved for love vs. sharp-tongued tech upstart with irresistible charm]
Lin Youyou was tired of being a good girl. To defy her family's pathological control over her, she did something wildly out of character.
She set her sights on a conceited playboy adored by everyone.
She seduced him into one wild night, and their ambiguous relationship began.
This girl had unusual ideas. She was a real oddball.
She insisted on splitting the hotel bill, splitting the dinner bill, and even fighting him over the cost of the supplies. She never spent the night with him outside his place, and when they met at school, she pretended not to know him.
Lin Youyou knew exactly what she wanted. Her secret relationship with Lu Jinghuai was no reason to tie their interests together. They each got what they needed, and once they were out of bed, they only had to play the most familiar strangers.
At first, Lu Jinghuai found her amusing and thought of it as a game. He never expected to be the one who fell first.
"My cat can do a backflip. Want to come see?"
"The pothos at my place is dying. Come over and hold a memorial service for it."
"Today is the bedsheet's first anniversary. Come to its birthday party."
He came up with all kinds of excuses every day to invite Lin Youyou over.
On the surface, Lin Youyou was a good girl untouched by worldly concerns who only listened to her mother.
Only Lu Jinghuai knew she was a total knockout.
One night, as they lost themselves in each other, Lu Jinghuai asked when she would give him a proper title.
Lin Youyou said to wait a little longer.
Then she vanished from his world without a trace.
Five years later, Lin Youyou had settled abroad.
The tech upstart sat in the front row, glaring with a fierce expression at her red lips as she gave her speech.
After the speech, Lin Youyou was tossed into a private room.
Lu Jinghuai looked down at her and lifted her chin. "Lin Youyou, you really are ruthless."
