Xia Chuwei had always known she was meant to marry Xiao Beichen. As his fiancée since childhood, she grew up revolving around his world, believing he was her destined one. But on her eighteenth birthday, her world shattered when she overheard him say:

“It’s all arranged by our families. If not for gratitude, why would I marry her? To me, she’s just a sister.”
“Beichen only loves Xueqing. Why else would he abandon Chuwei on her birthday just to welcome Xueqing back? He didn’t even show up to register their marriage today.”

Heartbroken, Xia Chuwei disappeared without a trace.
By the time Xiao Beichen realized his mistake and wanted to make things right, she was gone.
When they met again, she was holding hands with his long-time rival, smiling sweetly, calling him “gege”—a term she once used only for Beichen.
Xiao Beichen’s eyes turned red with jealousy.
“Chuwei… I’m not your brother.”
