How to Write a Love Haiku
Start with a moment, not a feeling. "I love you so much" isn't a haiku, it's a greeting card. But "your scarf still smells like / the restaurant where we first / learned each other's names", that's a scene. Ground your love haiku in something concrete and sensory before you ever think about syllable counts.
Once you've got your moment, draft it in plain language. Don't worry about the 5-7-5 structure yet. Just write what you see, hear, or feel in that memory. Then start shaping. Swap words for shorter or longer synonyms. Cut unnecessary articles. A common mistake is padding lines with filler words like "very" or "so" just to hit the syllable count, and readers can always tell.
Another trap is being too abstract. "Love is like the wind" tells your reader nothing they haven't heard a thousand times. Get specific. What does your love feel like? What does this particular person do that nobody else does? The best haiku about love succeed because they feel like they could only have been written by one person about one other person.
The middle line matters most. It's the longest, and it carries the poem's weight. Think of lines one and three as the frame, and line two as the painting itself. Read your haiku out loud and listen for natural pauses. If it sounds like you're rushing through a line or awkwardly stretching one out, the syllable distribution probably needs work.
