Finding a show that actually talks about sex without making everyone in the room want to crawl into a hole and die is rare. Netflix’s Taiwanese original, Let's Talk About Chu, managed to do just that. It’s messy. It’s loud. It’s weirdly relatable. But honestly, the reason it works isn't just the bold script—it’s the cast of Let's Talk About Chu and how they handle topics that usually make traditional families sweat.
We’re talking about a culture where "the talk" usually consists of silence and a heavy focus on academic achievement. Then comes Chu Ai and her chaotic family to blow that all up.
Chan Tzu-hsuan: The Heart of the Chaos
Chan Tzu-hsuan plays Chu Ai, a waxer by day and a sex-positive YouTuber by night. She’s the anchor. If she didn't sell the vulnerability behind the "no-strings-attached" bravado, the show would’ve felt like a hollow attempt to be edgy. Chan isn't a veteran with fifty credits to her name, which actually helps. She feels fresh. Her chemistry with Kai Ko is what keeps the "will-they-won't-they" trope from feeling exhausted.
Chu Ai’s mantra is basically "make love, not fall in love," but we all know how that usually goes in dramas. What’s interesting is how Chan portrays the internal friction of a girl who wants to be modern and liberated but still lives in a house where her parents are effectively roommates who hate each other. She’s the personification of the Gen Z struggle in East Asia—trying to find a new identity while the old one is still breathing down your neck.
Kai Ko and the "Part-Time" Romance
Then there's Kai Ko. If you’ve followed Taiwanese cinema for more than a minute, you know Kai Ko. He’s had a rollercoaster of a career, from the heights of You Are the Apple of My Eye to some pretty public personal setbacks. In this show, he plays Ping-ke, Chu Ai's "friends-with-benefits" partner.

Kai Ko has this specific energy. He’s charming but looks like he hasn't slept in three days. It works perfectly for Ping-ke. He isn't some polished K-drama lead who does everything right. He’s a guy with his own baggage, and his interactions with the cast of Let's Talk About Chu provide some of the most grounded moments in the series. They don't just have sex; they have awkward conversations about why they aren't dating, which is way more realistic.
The Supporting Players You Might Recognize
You can’t talk about this show without mentioning the older generation. It’s easy to focus on the young, attractive leads, but the parents are where the real tragedy (and comedy) lies.
- Miao Ke-li: She plays the mother. If you’ve watched Taiwanese soap operas (Hokkien dramas), you know she is royalty. She brings that "loud but loving" energy that is so specific to Taiwanese moms. Her character's obsession with her kids' lives is really just a mask for her own failing marriage.
- Hong Sheng-te (Tony Yang): Playing the father, he represents that stoic, slightly useless patriarch who doesn't know how to communicate. His arc is actually one of the quietest but most impactful.
Why This Ensemble Works Better Than Other Rom-Coms
Most shows pick a lane. They are either a raunchy comedy or a tear-jerking family drama. This cast blends them. Wu Chien-ho, who plays the brother Chu Yu-sen, deserves a massive shout-out. His storyline involves a complicated, somewhat secretive relationship that adds a layer of "taboo" that the show handles with surprising grace.
The dynamic between the siblings is arguably better than the romances. They fight. They judge each other. They hide things. It feels like a real house. When you look at the cast of Let's Talk About Chu, you’re seeing a cross-section of Taiwanese acting talent—from the legendary Miao Ke-li to the rising star Chan Tzu-hsuan.

Beyond the Screen: The Chemistry
Rumors always fly about cast members dating, but in this case, the off-screen camaraderie seems to have fueled the on-screen comfort. During the press tours in Taipei, the cast talked extensively about the "intimacy coordinators" on set. That’s a relatively new thing for Taiwanese productions. It meant that the actors felt safe, which is why the scenes feel intimate rather than exploitative.
Kinda makes a difference, right?
When actors aren't worried about crossing boundaries or being uncomfortable, they can actually act. You see it in the way Chu Ai and Ping-ke look at each other. It’s not just "hot"—it’s connected.
The Social Impact of the Cast's Performances
Taiwan became the first in Asia to legalize same-sex marriage, but social stigma doesn't just vanish overnight. The cast of Let's Talk About Chu takes these lingering stigmas head-on. By having well-known actors like Kai Ko and JC Lin (who plays a significant role in the brother's storyline) engage in these topics, it normalizes them for a wider audience.

It’s not just a show for "kids." My friend told me her mom actually watched it and, while she complained about the "boldness," she didn't turn it off. That’s the power of a good cast. They draw you in with their faces and keep you there with their performances.
Breaking Down the Chu Family Tree
- Chu Ai (The Protagonist): The youngest. Sex-ed vlogger.
- Chu Pan (The Older Sister): Played by Kimi Hsia. She represents the "perfect" daughter whose marriage is actually falling apart because of a lack of intimacy.
- Chu Yu-sen (The Brother): The academic overachiever with a secret life.
- The Parents: The foundation that is slowly cracking.
Realism Over Glossy Perfection
Let’s be honest. Most Netflix shows look too clean. Everyone’s hair is perfect even when they wake up. In Let's Talk About Chu, there’s a bit of grit. People sweat. They look tired. The apartments look like people actually live in them—cluttered and a bit cramped.
This groundedness is carried by the actors. JC Lin, for example, brings a ruggedness that contrasts with the more "idol" look of other cast members. He plays a guy who works at a traditional market. It’s a nice reminder that life in Taipei isn't all Xinyi District skyscrapers and bubble tea shops. It’s also wet markets and old buildings.
Actionable Takeaways for Fans and Viewers
If you’ve finished the series and you're looking for more, or if you're just starting, keep these things in mind to get the most out of the experience:
- Follow the Cast on Socials: Many of them, especially Chan Tzu-hsuan (@tzuhsuan.chan) and Kai Ko (@kaikaiko), share behind-the-scenes looks at the "intimacy training" they did, which gives a lot of context to the show's production.
- Look for Their Previous Work: To see the range of this cast, watch A Sun for Wu Chien-ho or The Last Verse for Fu Meng-po (who plays the husband of the eldest sister). It shows how versatile these actors really are.
- Pay Attention to the Side Stories: The show is called Let's Talk About Chu, but the B-plots involving the siblings are often more emotionally heavy than the main romance. Don't skip the "boring" family dinner scenes—they contain most of the foreshadowing.
- Understand the Context: This isn't just a "sexy show." It’s a critique of the "hush-hush" culture in Taiwan. Viewing it through that lens makes the performances of the parents much more heartbreaking.
The cast of Let's Talk About Chu successfully pulled off a difficult balancing act. They made a show about sex that is actually about love, communication, and the terrifying realization that our parents are just people who are as lost as we are.
Whether you came for the viral TikTok clips or the promise of a bold new drama, the acting is what makes it stick. It’s a snapshot of a changing society, led by a group of actors who aren't afraid to get a little bit messy.
