因为没有结尾才更完美
[yīn wéi méi yŏu jié wĕi cái gèng wán mĕi]
This roughly stands for 'it is perfect because it has no end', meaning sometimes things left incomplete may be perceived as better off than those finished. A story unfinished may hold more possibilities, or emotions unspoken may preserve purity. It's an abstract but interesting way to view imperfection.
