Xu Jinxi * Yu Hanbo
[A cheerful girl who flirts without realizing it + an athletic, secretly flirtatious green-tea guy; male lead is reborn; childhood friends + bickering lovers + love that grows over time + both leads have no previous sexual relationships]
[Content warning: The heroine had a boyfriend in her previous life, but they never had any intimate interactions]
Before he was reborn:
When Xu Jinxi was taking the college entrance exam, disaster struck her family. She later fell in love with Xia Tongrui, and they were together for ten years.
When Xu Jinxi died, Xia Tongrui had fallen for someone else and was about to marry Qu Zhixin.
After learning of Xu Jinxi's death, Xia Tongrui sneered at Qu Zhixin: “Your beloved is dead.”
Qu Zhixin mocked Xia Tongrui: “As if she wasn't your beloved too.”
Furious, Yu Hanbo drove them both away and began to regret moving to Germany all those years ago.
After he was reborn:
Yu Hanbo returns to China first and stays by Xu Jinxi's side, stopping her from ever crossing paths with that scumbag and that awful woman. As they spend more time together, he comes to understand his own feelings.
What if Xu Jinxi still doesn't get it?
Then seduce her, of course. (Yu Hanbo shows off his pecs and abs) (attempts seduction)
But a series of strange events unfold, and Xu Jinxi inevitably finds herself following a predetermined path, forcing him to think hard about how to break the pattern.
The male lead is reborn.
