Kim's poem starts with a familiar phrase, "reach for the stars," and turns it into something sadder. The stars are falling, the sky is crying, and the speaker's own self is fading. Each stanza follows the same pattern: she reaches for something bigger than herself, and it slips away or breaks in her hands.
The speaker seems exhausted and unseen. People enjoy the stars' shine without caring that they're running out of time, and nobody notices the sky weeping. The poem suggests she feels treated the same way. She hides her own tears until she's asleep, perhaps because others do so much for her that she feels she can't complain.
By the last stanza, the reaching turns inward. The person in the mirror doesn't realize they're failing, and the images of blood and a dam full of tears suggest pain that is close to overflowing. The mood is heavy, quiet and lonely, with time stretching painfully: seconds feel like years.
