Dae's poem is about faith in a love that can't be seen, heard, or touched. The speaker admits that none of their senses can find it, yet they feel certain it exists. To explain that certainty, they point to things we trust without proof: the sun rising, winter giving way to spring, waves hitting the shore again and again.
The middle of the poem gets more honest about what hides love from view. Pride, ego, and distance cast shadows over it, and the word "lurking" suggests love is waiting patiently rather than gone. The speaker believes these obstacles can be overcome, but only "if you allow it," which sounds like a quiet invitation to the person they're addressing.
The ending adds a touch of longing. The "bittersweet taste" of your love suggests the speaker misses it at times, and that the absence stings. Even so, the mood stays calm, steady, and hopeful. The speaker isn't desperate, just sure.
