铜雀锁金钗

To love someone deeply is to want nothing more than to lock them away with a golden padlock. The moment Duan Yelin first laid eyes on Xu Hang, he wanted to lock him away and keep him hidden in a golden chamber and, in fact, that’s exactly what he did. Xu Hang was reluctant, but he wanted to live; he still had so many things left to do, so in the end, he entered the Little Copper Pass. It was only much later that Duan Yelin realized what he had locked away was not a cool and aloof golden finch, but a cold, sharp golden hairpin. (Source: Tencent, translated)
