[Sweet romance + second male lead's regret and pursuit + male lead wins his friend's childhood sweetheart]
A scheming, arrogant male lead × a sweet, soft-hearted female lead
An Xing had secretly loved her childhood friend Gu Zeyu for ten years. Watching him go through one girlfriend after another, she thought that one day it would finally be her turn. But his indifference and the various schemes of a two-faced woman wore her down, until she gradually realized that a man a thousand times better than Gu Zeyu had been by her side all along, protecting her.
By the time Gu Zeyu realized how he felt, his childhood sweetheart had already been swept away by his best friend.
“An Xing, come back. I regret it.”
“Sorry, buddy. An Xing is my fiancée now.”
From the female lead's perspective, it's love that grows over time.
From the male lead's perspective, it was love at first sight, followed by a long-planned pursuit.
