[yĭ zhăng fā jí yāo nĭ què qīng xīn yú tā]
This nickname tells a bittersweet love story where the user has grown their hair long as a symbol of waiting or devotion, possibly to win someone's affection, yet the loved one has fallen in love with someone else instead. This is a common theme found in various Chinese romantic stories where a female character grows her hair out in hopes of attracting or impressing a lover.
