十年后伴你穿婚纱十年前伴你穿校服
[shí nián hòu bàn nĭ chuān hūn shā shí nián qián bàn nĭ chuān xiào fú]
Translating to 'Wearing wedding dress together ten years later; wearing school uniforms together ten years before'. This signifies a promise of being with someone not just in youthful times marked by education but also in future adult commitments like marriage, indicating loyalty, love continuity over long periods spanning from student years through maturation and beyond.
