Rain is treated here as something with two faces. The speaker hears it as loud, yet also "crystal clear yet so blurry," a contradiction that captures how rain can sharpen the world and smear it at once. That blur seems to be the point: rain hides our pain and sorrow, and next to it our tears look faded, almost unnoticeable.
The middle of the poem sets two moods side by side. Rain can feel like a "happy romantic weather" or a "sad mournful shiver," and the poem doesn't choose between them. The feeling it brings lingers, but only "just a while longer," which gives the sense of something fleeting.
The ending turns darker. Rain's "gentle touch" causes us to "wither," so the softness that comforts us also wears us down. (The poem writes "it's" where "its" is meant.) The overall mood is wistful and bittersweet, a comfort that carries a quiet sadness inside it.
