我姓苏却一直不肯输掉你
[wŏ xìng sū què yī zhí bù kĕn shū diào nĭ]
'My surname is So (Su), yet I won’t let you go.' It implies even with their fate written in their name ('Su', in Chinese sounds similar to 'suffer') they are still unwilling to give up on you despite challenges. A poetic way of expressing determination and persistence towards someone.
