Design a Meet-Cute With Consequences
The meet-cute does more than introduce your leads. It plants the seed of the entire relationship. The best meet-cutes reveal character immediately and create a small, memorable humiliation or vulnerability that the characters will have to live down for chapters. Don't settle for “they bumped into each other.” Ask what scenario forces both characters to show who they really are right away, then engineer the collision around that. The awkwardness should be specific enough to make readers smile every time it gets referenced later.
