Life itself is not an easy thing. Wouldn't it be even more sad if we had to care about everything and pursue it. Xia Yi has known that life is not easy since she was a child. If you want to get something, you have to give. If you want to make demands, you have to exchange what the other party needs. It's not that she is naturally smart. Who doesn't really grow up like a child? It's not that her family's financial constraints make her so "sensible". Are the things you are doing now necessary or are you just struggling to pass time? If she hadn't met so many people around her, maybe she wouldn't have had enough courage and confidence to make the so-called meaningless struggle.
