The 'Couple Fit' and Finding the Right 'Wrong' Partner

Lee Sung Jin has become one of the most compelling storytellers exploring the contradictions of modern relationships. His satirical dark-comedy drama Beef captures the chaos, complexity, and emotional volatility of being human—and the relational patterns that emerge from it.

In his latest series, he turns his attention to something many couple therapists will recognise instantly: archetypal relationship “fits.”

Here are the two ‘couple fits’ depicted in Beef:

Babes in the Wood

You’ve probably seen this couple before. They often look alike, seem deeply aligned, and appear blissfully happy.

Their bond is organised around keeping “badness” outside the relationship. Conflict, anger, and disappointment belong to the external world—not between them. Their relationship functions almost like a protective shelter, where difficult feelings are denied or minimised.

To them, the threat is always “out there”: the big bad wolf of the world.

But what happens when what’s been kept outside inevitably finds its way in?

Cat and Dog

As the phrase suggests, this couple fights like cat and dog.

Think Who’s Afraid of Virginia Woolf?—a relationship fuelled by conflict, where intimacy and hostility become intertwined. The hallmarks are anger, rejection, criticism, and emotional warfare.

Unlike the Babes in the Wood couple, these partners are hyper-aware of what feels “bad”—but only in each other. Their relationship becomes a battleground where vulnerability is regulated through conflict.

And yet they often stay together. Not because it works, but because the alternative—leaving and risking no “better” relationship—feels more frightening.

In both relationship fits, something important is happening: each couple is organised around denied parts of themselves.

In one, badness is expelled outward.

In the other, it is projected onto each other.

This is where couple therapy helps—not by fixing the relationship, but by helping the couple “re-fit” it.

At the heart of the series is a provocative question:

Are we meant to find the right ‘wrong’ person?

At first glance, it sounds contradictory.

But the idea isn’t about settling for someone incompatible. Rather, it is to recognise that some degree of incompatibility is inevitable and to understand how complementarity works within a relationship. Every relationship contains friction, difference, and disappointment. The challenge is not to eliminate these tensions, but to determine whether they create growth and balance or persistent harm and disconnection.

So the real question becomes:

Whose flaws can you live with? Whose wounds can you understand? And whose patterns mirror your own?

This question plays out through two couples.

The Cat and Dog pairing—Joshua and Lindsay—represent an established marriage where each partner’s “wrong” feeds the other’s: ego, resentment, defensiveness, control. Their dysfunction has become normalised.

Lindsay reassures herself:

“Couples fight, it’s normal. We’re normal.”

And perhaps she’s right—to a point. Conflict is normal. It can even be healthy. But when does conflict stop being repairable tension and become toxicity?

Lindsay later tells the younger couple:

“All the couples I know that last, they’ve really had at it. And it’s actually the ones that don’t, where someone’s usually hiding something. The bad does have to come out somewhere.”

It’s a striking line because it contains both truth and distortion. The “bad” does need somewhere to go. But how it emerges matters.

Then there’s the Babes in the Wood couple—Ashley and Austin.

Younger, idealistic, and seemingly harmonious, they watch Joshua and Lindsay’s marriage unfold like both a cautionary tale and an uncomfortable mirror.

It forces a difficult question:

Are we actually different—or just earlier in the same cycle?

Shaken by Lindsay’s assertion that fighting is essential, Austin turns to Reddit in search of reassurance:

“Fiancée and I never fight. Why?”

The responses unsettle him.

What if the absence of friction isn’t harmony—but avoidance?

And that’s where the brilliance of the series lies.

By placing these two relational styles side by side, the show dismantles the fantasy of the “perfect match.”

Instead, it suggests something deeper:

You don’t find someone who fixes your chaos. You find someone whose chaos interlocks with yours. And that can become either connection and growth — or mutual destruction.

The idea of a “kindred spirit in despair” feels central here.

The series seems to argue that deep relationships aren’t built on solving each other’s wounds, but on recognising them — and choosing to stay engaged anyway.

That is the “right wrong” person: the person who sees your worst patterns clearly and still stays in relationship with you. For better or worse.

The darker implication, though, is that perhaps we’re never really choosing between “right” and “wrong” partners. Perhaps we’re only ever choosing between different versions of wrong—disguised as compatibility, chemistry, or timing.

Through this lens, the series feels less like a romance story and more like a critique of the fantasy that love has a formula at all.

The message it sends is that love isn’t about finding the right person, it’s about finding the person whose imperfections force you to confront your own.
