So, change the description to something like below, and rewrite the examples to remove the labels?
is a Love Trope
that extends over several genres. Two characters make plans to get together, but once the time arrives, one of them never show up. This is almost always about a romantic date (or what one or both of the characters hope it is), but can be about a platonic couple, such as family.
The outcome varies a lot, depending on genre, setting, what kind of characters are involved, etc. On the more idealistic side, there may be a good reason for not showing up, and the character may be forgiven. On the more cynical or tragic side, there often isn't a good reason, and the relationship ends there. Sometimes it's also set up from the beginning.
