念你如初悔知当初
[niàn nĭ rú chū huĭ zhī dāng chū]
This phrase expresses deep feelings for someone ('thinking of you just as I did in the beginning'), accompanied by regret over actions or decisions made during initial meetings ('regret that I know now what I wish I had done back then'). It reflects unfulfilled longing or love that turned to remorse.
