穿过心海相爱到永远
[chuān guò xīn hăi xiāng ài dào yŏng yuăn]
Love Through the Heart Ocean Forever. '穿' here means to traverse through, this is often used poetically, it's meant to say love can transcend distance and time (like an ocean of hearts), symbolizing an undying devotion and wishful thinking for everlasting love.
