Let’s be real for a second. If you’ve spent any time reading the Solo Leveling manhwa, you probably noticed that the romance isn't exactly front and center. It’s a series about a guy getting absurdly strong and turning his enemies into loyal shadow soldiers.
Yet, the connection between Sung Jinwoo and Cha Hae-In remains one of the most talked-about parts of the entire story.

Some fans call it rushed. Others think it’s the perfect, subtle backdrop to a world-ending war. Honestly, it's a bit of both. But if you look closely at the light novel—and especially the newer Ragnarok sequel—there’s a lot more depth than just "the two strongest people in Korea decided to date."
It’s actually a story about the only person who could look at a literal god of death and see a human being.
The Smell That Started Everything
It sounds weird when you say it out loud. Hae-In’s interest in Jinwoo didn't start because he was handsome or powerful. It was because he didn't smell like rotting garbage.
See, S-Rank Hunters have this hyper-sensitivity to mana. To Hae-In, every other hunter reeked of a foul, nauseating scent. It made her life miserable, forcing her to cover her nose with a handkerchief constantly.
Then she meets Jinwoo.
Unlike everyone else, he smells "pleasant." It’s a tiny detail, but it’s the catalyst. She becomes curious. That curiosity leads her to follow him, eventually seeing him in action during the High Orc raid. While everyone else was terrified of his power, she was fascinated by the man behind it.
Why Their Connection Is Deeper in the Novel
If you only read the manhwa, you might feel like they barely talked before the world reset. The light novel is a different beast entirely. It gives us Jinwoo’s internal monologue, which is way more emotional than his "stoic badass" persona in the art.
There’s a specific scene where they go on a date to a theme park. In the manhwa, it's cute. In the novel, it’s a moment of pure vulnerability. Jinwoo realizes that with his power, he is becoming something other than human. Hae-In is his anchor. She’s the only one who doesn't treat him like a weapon of mass destruction or a savior. To her, he's just the guy who smells nice and looks a bit lonely.
They actually spend a night in the woods before the final battle with the Monarchs. The manhwa keeps it very PG—they just sleep next to each other. But the novel hints at a much deeper intimacy. It’s their "final night" moment, and it makes his decision to reset the timeline even more heartbreaking. He was willing to erase her memory of him just to give her a world where she didn't have to fight.

The Reset: Starting Over From Zero
When Jinwoo uses the Cup of Reincarnation, he wipes the slate clean. 10 years of history? Gone. The Gates? Never happened.
In this new timeline, Jinwoo is a detective, and Hae-In is a normal high school track star. He could have walked away. He could have let her live a life where they never met. But destiny—or maybe just Jinwoo’s persistence—had other plans.
He tracks her down at a track meet. He doesn't use his powers. He doesn't show off. He just approaches her.
What’s crazy is that even without her memories, Hae-In feels a connection. It’s that "scent" again, or a lingering soul-memory of the man who saved the world for her. They eventually marry and have a son, Sung Suho.
What Happens in Solo Leveling: Ragnarok?
The story doesn't end with a "happily ever after" in the traditional sense. In the sequel, Solo Leveling: Ragnarok, things get pretty intense.
- Jinwoo is gone: He’s currently in the cracks between dimensions, fighting a never-ending war against the Itarim (Outer Gods).
- Hae-In is a powerhouse: Even in the new world, she isn't just a "trophy wife." In Ragnarok, she eventually regains her strength, reaching a level comparable to a National Level Hunter.
- Suho’s Journey: Their son, Sung Suho, becomes the protagonist. He inherits his father’s Shadow Monarch potential, but Jinwoo actually sealed his memories and powers so he could grow up normally.
There’s a particularly heavy moment where Hae-In disappears while Jinwoo is away fighting. This leaves Suho to step up and find his parents. It adds a layer of "family legacy" that the original series lacked. We see that the bond between Jinwoo and Hae-In wasn't just a plot device; it was the foundation for the next generation of protectors.
Common Misconceptions About the Couple
I see people online saying Hae-In is "boring" or "weak." Honestly, I think that’s a misunderstanding of her role.

She was the only S-Rank who stepped up to help Jinwoo in the Double Dungeon during the Architect's final test. She was willing to die for him when he was still a mystery. She isn't a damsel; she’s the only person who can stand beside him without being overshadowed by his "aura."
Another big one: "Jinwoo doesn't love her."
If he didn't love her, he wouldn't have spent 27 years in a void fighting monsters just to ensure she could live in a world with blue skies. That’s the ultimate "act of service" love language.
How to Follow Their Full Story
If you want to see the full evolution of their relationship, you can't just stick to the anime. The anime is great, but it's only at the beginning. Here is how to get the full picture:
- Read the Light Novel: Specifically the epilogue chapters (243 and onwards). This is where the marriage and Suho’s birth are detailed.
- Check out the Side Stories: The manhwa has "special episodes" that cover their life in the reset timeline. It’s pure wholesome content.
- Dive into Ragnarok: The webtoon/novel for Solo Leveling: Ragnarok explores their legacy and Suho’s attempt to reunite the family.
By focusing on these sources, you'll see that Sung Jinwoo and Cha Hae-In aren't just a random pairing—they are the literal heart of the Solo Leveling universe.
If you are looking to see their first meeting animated, keep an eye on the upcoming seasons of the anime, where their "scent-based" chemistry starts to take center stage. You can also play Solo Leveling: Arise to experience unique interactions between them that aren't in the main story.
