The speaker is talking to someone they care about, someone who seems to be struggling with how they see themselves. The wish is simple: that one day this person will look in the mirror, smile, and feel real love for who they are. The mention of scars suggests pain the person carries, and the speaker pictures those scars gone. The scars could be physical or emotional, and the poem leaves that open.
What makes the poem moving is its last two lines. Up to that point it reads like a gentle wish, but then the speaker admits, "it's hopeless / but I'm still hoping." That admission adds doubt and a bit of sadness. The speaker doesn't pretend things will definitely get better, and they can't fix this person's pain themselves. They keep hoping anyway. The short, plain lines and lowercase style make the mood quiet and tender, like someone saying something honest under their breath. It ends up feeling both sad and stubbornly loving.
