婚约（一不小心爱上你）

Premise

Both of them are on blind dates for the same reason: they need to get married. The first dates fail, and then the two of them compare notes and discover their goals line up exactly. Rather than keep searching, they choose a fast wedding. It's a marriage of convenience, built on a practical agreement. Their families and friends make the first weeks hard, questioning the union and making life difficult at every turn.

Characters

The leads start out practical and a little guarded, treating marriage as a plan rather than a romance. The synopsis doesn't give them fixed backstory names, so the story leans on their roles: the reluctant husband and the wife who wants stability. Relatives and close friends act as the pressure in the show, pushing the couple to prove the marriage is genuine. Their growing respect for each other becomes the quiet engine of the story.

Main arc

The opening act is built on a shared goal and a bargain. The obstacles come from people who doubt the couple and keep making things harder. Living together gradually shows each lead the other's strengths, and the friction slowly turns into attraction. The synopsis describes the sparks catching fire, and the arc resolves in a sweet, settled start to married life. The emotional payoff is in watching two people who planned a strategy end up falling for each other.

Themes & tropes

The marriage of convenience is the core trope, and the show turns it toward real romance. The billionaire label from the genre list colors the polished lifestyle, though the synopsis is more concerned with family pressure than wealth. Trust builds through small domestic moments rather than grand gestures. The story suggests that a practical beginning can grow into something lasting.

Why viewers watch

This is for viewers who enjoy the arc from convenience to love and a warm, low-stakes romance. The series doesn't rely on dramatic twists. It focuses on the believable change in how two strangers see each other as they share a home and a family that won't leave them alone. It's an easy, comfortable watch across its 90 episodes.
