原以为我爱你你就不会走
[yuán yĭ wéi wŏ ài nĭ nĭ jiù bù huì zŏu]
'Yuan Yi Wei Ai Ni Ni Jiu Bu Hui Zou' translates to 'I originally thought that if I loved you, you wouldn't leave me'. This nickname is filled with the regret and pain after being left by someone they loved deeply, reflecting an experience of unreturned love.
