The speaker of "Soon Enough" is caught between two painful ideas: that the people they care about will drift away, and that the only way to stop it is to trap them. The poem opens with a kind of grim confidence. "Soon enough I'll find them" and "soon enough they'll stray" sound almost like a prediction the speaker has made many times. The third line turns darker, with ropes and locks, as if holding on tightly is the only answer to being abandoned.
Then the tone drops. "Like they always do" suggests a long pattern of people leaving, and it makes the earlier threat feel less like cruelty and more like desperation. The speaker seems to know that binding people won't actually work, because the last two lines admit the result anyway: crying alone under the moon.
The mood is lonely, tense and quietly sad. The repeated "soon enough" works like a countdown, making the loss feel certain before it even happens. Underneath the harsh words, the poem reads as a fear of being left, not a wish to harm.
