I see it more like the exquisite corpse exercise.
From wikipedia:
Exquisite corpse, also known as exquisite cadaver (from the original French term cadavre exquis) or rotating corpse, is a method by which a collection of words or images is collectively assembled. Each collaborator adds to a composition in sequence, either by following a rule (e.g. "The adjective noun adverb verb the adjective noun", as in "The green duck sweetly sang the dreadful dirge" or by being allowed to see only the end of what the previous person contributed.
In either situation, the same unrecognizable confusion arises. It's is only when we are given the key to the corpse (or the set of rules, e.g. "The adjective noun adverb verb the adjective noun" that we can gain some clarity on why the resulting sentence, or relationship in our case, worked grammatically. Unless looked upon in a very nonsensical and metaphorical way (for instance, how we viewed our partners via our own personal flaws, or own own idealization of the relationship as 'special', 'different', 'final', something generated from the exercise would never be used in a realistic way.
Works in literature, but literature is an embodiment of the human imagination. A good relationship can't be this. It is not practical. We need need to think about our sentences, to complete the simile.
