One accidental plus-one to a wedding, one wildly unconvincing "we're together, actually", and suddenly a reader is cancelling plans to finish the book. If you've ever wondered why do readers like fake dating, the short answer is this: it delivers maximum romantic chaos with a guaranteed emotional payoff. It is messy, flirty, structured, and just self-aware enough to be irresistible.

Fake dating is one of those tropes that keeps surviving every trend cycle because it understands the assignment. Readers know the couple are pretending. The characters know they're pretending. Everyone also knows somebody is going to catch feelings and make it everybody's problem. That delicious inevitability is not a flaw. It is the whole point.
