Summary
Xie Chenxian has looked after Shen Jiu all her life, from cooking her meals to applying lip balm after their kisses. She thinks they are the couple everyone envies—until she overhears him call her a child and dismiss the idea of her dating. If he only wants to be her big brother, she will stop relying on him. She carries her own bag, washes her own clothes, and arranges to study abroad alone. But the more independent she becomes, the more he falls apart. At the airport, he finally asks: doesn’t she need her big brother anymore?
