一十七画书作无缘只两字一十九笔有缘相聚莫别离
[yī shí qī huà shū zuò wú yuán zhĭ liăng zì yī shí jiŭ bĭ yŏu yuán xiāng jù mò bié lí]
This elaborate nickname means 'In seventeen strokes of writing fate hasn't brought us together with only two words but with nineteen strokes and fated encounter don’t depart.' It's metaphorically expressing the idea of how characters come together forming destiny; thus it represents hope for reunion or meeting despite initial unacquaintedness.
