It's possible I'm reading too much into this, but I think what stuck with me the most, is that you chose vermillion (a bright colour, full of vigor) to describe their heart, and you chose wine (a darker hue, almost purple depending on the exact shade) to describe yours. In diagrams of the heart, red/vermillion can be used to show oxygenated blood, which indicates that they're full of life, or you see them that way, and deoxygenated blood is shown as blue. Blue and red mixed together make purple, and that indicates you're full of life and not at the same time. You see them through rose-tinted glasses, and that's further cemented by the ending, pulling on their sleeve, reaching for love, like a child. A quality I think that is necessary for us to hold onto in life. Anyway, rambling aside, this is a very lovely write.
