Shangguan Zhi thought she would end up with Pei Xuan, the childhood friend she'd grown up with. She imagined they'd fall in love and get married, but after she confessed her feelings to him at high school graduation, she never heard from him again. She gave up on him.
But when Shangguan Zhi had moved on and was ready to start a new relationship during her sophomore year of college, he came back.
From the hero's perspective:
He met her at a social gathering and couldn't get her out of his mind. He began pursuing her in secret, and later, just when he thought he was finally about to win her heart, he learned that the girl he loved had a childhood friend she'd kept in her heart for years.
He thought to himself: So what? He's just her childhood friend, right?
