Details I remember:
It’s a Chinese full-color romance manhua set in modern-day China.
The female lead receives a phone call from her future self (10 years later) warning her about her fiancé cheating.
The call changes her perspective — she starts improving herself, becomes more confident, and moves on.
Later, her future self somehow travels back to her timeline (I’m not sure why).
The FL’s best friend also had a side story: she dated a jerk who left her after she got pregnant, then he chased a rich girl. But later the best friend met a kind, slightly chubby guy who truly loved her.
The story was already completed when I read it, around 5–6 years ago (maybe 2018–2020).
