I finished Take Charge of My Heart (나를 충전해줘) this week, and the ending was my favorite part of the whole show. If you’ve watched the finale and want to make sure you caught everything, or you just want to know how it ends before you commit to 10 episodes, this is the full breakdown.
This post is all spoilers, from the first line to the last. If you want my spoiler-free take first, read my full review.
The short answer
Yes, Ho-rang and Bo-bae end up together. Ho-rang survives, his surgery goes well, and he doesn’t need any more surgeries after it. Bo-bae uses up all of her electricity saving his life, and when it’s gone, it doesn’t come back. They get approval from both families, Bo-bae becomes a successful writer, and the last we see of them, they’re living together in the same house in Seoul.
The longer version has one last twist before that happy ending, so let’s walk through it.
Where things stand going into the finale
Quick refresher on the rules of the show. Ho-rang (Kim Young-kwang) is a TS Group heir living with an artificial heart device whose battery keeps running down until his next surgery. Bo-bae (Chae Soo-bin) is a drama writer who’s produced electricity ever since she was struck by lightning as a kid, and he’s the only person her touch doesn’t hurt. Being near her recharges his heart, so the two of them sign a three-month contract: she keeps him alive until surgery, and he helps her with the romance script she has no experience to write.
By the final episodes, the contract has turned into a real relationship, which is exactly when the outside pressure piles on. The biggest threat inside TS Group is Ho-rang’s cousin, Choi Do-yoon (Jung Jae-kwang), the family troublemaker who’s been butting heads with him the whole series.
The anniversary night
Things come to a head at TS Group’s 30th anniversary celebration. According to finale recaps, Do-yoon spikes Ho-rang’s drink and kidnaps Bo-bae to keep her away from him. She manages to escape and rushes to the event, but by the time she gets there, Ho-rang has collapsed on stage and is in critical condition.
This is where the show’s whole premise pays off. Bo-bae’s electricity has been treated as a curse since the very first episode, the reason she could never touch anyone. In this moment, it’s the one thing that can save him.
Bo-bae’s choice
To keep Ho-rang alive before he goes into surgery, Bo-bae pours everything she has into him, essentially using her own body as an emergency shock. It works. He makes it into surgery, and the surgery goes well. Even better, he doesn’t need surgeries any longer after this one, which means the whole reason for their contract is gone.
What Bo-bae doesn’t realize yet is what that surge cost her. She used up all of her electricity saving him, and it isn’t coming back. That detail matters a lot for what happens next.
Why Bo-bae leaves
Here’s the last twist. After the surgery, the doctor tells Bo-bae something she wasn’t ready to hear: now that Ho-rang’s heart is fixed, her electricity has become dangerous to him. The thing that used to keep him alive could now kill him.
So before he even wakes up, she leaves. She doesn’t say goodbye, she just goes, moving back to her parents’ home in a different town. From her point of view, staying close to him is now the one thing she can’t risk.
It’s a very K-drama move, the kind of last-minute separation I complained about in my review. To be fair to the show, this one is short, and it sets up the payoff.
How Ho-rang finds her
When Ho-rang wakes up and finds her gone, he misses her badly and starts looking everywhere for her. He eventually tracks her down at her parents’ place.
Meanwhile, Bo-bae has figured out something on her own. The electricity is gone. It doesn’t come out of her anymore, because she used every bit of it saving him before his surgery. So by the time he shows up at her parents’ door, the reason she left doesn’t exist anymore either.
Does Bo-bae lose her powers?
Yes, for good. The power she got from a lightning strike as a child is completely spent after she saves Ho-rang, and it doesn’t return.
That’s what makes the ending work. For the first time in her life, Bo-bae can touch anyone she wants without hurting them, and for the first time since the series started, Ho-rang’s life doesn’t depend on being near her. Several finale write-ups put it the same way: they stay together for love now, not for survival.
Meeting the parents
The scenes at Bo-bae’s parents’ house are some of the happiest in the whole series. They spend a very happy stretch of time there together, and Ho-rang gets her family’s approval for the relationship. Then the two of them leave together and head back to his place in Seoul.
After all the contracts, schemes, and near-death moments, it’s nice that the final stretch is just the two of them being normal and happy with her family around them.
The grandmother’s approval
On Ho-rang’s side, the hardest person to win over has always been his grandmother, played by veteran actress Kim Mi-kyung. By the end, she finally signals her approval, and what changes her mind is seeing Bo-bae’s humane, caring side for herself. That’s a satisfying beat, because it means Bo-bae wins her over by who she is, not by anything to do with her powers or the contract.
What happens to Do-yoon and TS Group
According to finale recaps, Do-yoon’s crimes come to light after the anniversary night, and Ho-rang ends up in control of the company. The show doesn’t spend much time on his downfall once the truth is out, which suits the rom-com tone. The focus stays on Ho-rang and Bo-bae.
Bo-bae’s career and the final scene
Bo-bae’s writing deadline was half the reason she signed the contract in the first place. She needed real romance experience to write a convincing romance script. By the end, she’s a successful writer, so in a way the contract gave her exactly what she was looking for, just not how she expected.
The final picture is the two of them living together in the same house. No battery, no contract, no countdown to surgery.
What the ending means
The way the show sets up its rules makes the ending click. At the start, the rule is simple: when they’re apart, his battery drains, and when they’re together, it recharges. Being close to her is literally what keeps him alive.
The finale flips that rule. Once his heart is fixed, being close to her becomes the danger, and that’s why she runs. Then the flip gets resolved in the cleanest possible way, because the power that bound them together, and then threatened to pull them apart, is gone. What’s left is just two people who chose each other. There’s a neat bookend in there too. A lightning strike gave Bo-bae her power when she was a child, and she gives the whole thing away in a single surge as an adult, for someone she loves.
Will there be a season 2?
As of now, Netflix hasn’t announced a second season, and I’d be surprised if there is one. There’s not much left to tell in the storyline. The finale wraps up every main thread, from Ho-rang’s health to Bo-bae’s powers to the TS Group power struggle, and there’s no cliffhanger. Take Charge of My Heart is based on a web novel, Hae Beon’s 나를 충전해줘 on Naver, and the drama tells a complete story in its 10 episodes. All of them have been on Netflix since October 9, 2026, so if you skipped ahead to the ending, you can still go back and watch how they got there.
The music behind the romance
If a song from the show has been stuck in your head, the OST includes Choi Sang-yeop’s “Turning Pages,” a romantic pop-rock track released the same day the series premiered. Korean reviews of the early episodes singled out the music as one of the show’s strengths, with a new track woven into nearly every episode.
My take on the ending
I liked it a lot. They get back together, his grandmother comes around after seeing Bo-bae’s humane side, Bo-bae becomes a successful writer, and they end up living in the same house. A happy ending, just the way I like it.
If you were on the fence about the slow first half, this is the part that makes it worth sticking around for. There’s something nice about a story that ends with the obstacles gone for good, and two people who get to just be happy together.
