承蒙时光不弃爱人永不分离
[chéng mĕng shí guāng bù qì ài rén yŏng bù fēn lí]
This could mean 'Thank you, time, for not abandoning me; my beloved one remains with me always'. It's about appreciating how time has treated the relationship between oneself and someone they cherish and hoping it will continue to do so forever.
