Daisyyyyy's poem is about unrequited love, the kind that makes no sense even to the person feeling it. The poem speaks to "you," and each pair of lines sets up the same contrast: he gives nothing, yet you keep giving. He ignores you, but you like him. He never speaks, but you dream of him. The steady pattern of "yet" makes the feeling seem almost stubborn, as if it won't listen to logic.
The speaker sounds like someone who understands the situation clearly but can't change it. There's a gentle frustration, and maybe a little self-mockery, in listing all the reasons this shouldn't work. The final line shifts, though. It ends with a question mark instead of a full stop, which suggests the speaker is asking, "Why did I do this?" The mood is wistful and a bit sad, but also honest. The title, "Love with no reason," sums it up: the heart doesn't wait for good evidence.
