Introduction
A quick heads-up before we dive in: despite the “K-drama” search buzz, S&X is actually a Japanese drama, not Korean — a live-action Netflix adaptation of Kisei Tada’s manga, led by former Sexy Zone idol Kento Nakajima in his second Netflix project. It’s a quiet, intimate character study about a sex therapist who’s remarkably good at helping everyone except himself, and it’s landed as one of the more thoughtful, boundary-pushing J-dramas Netflix has released this year.

Overview
Ichito Shimotori (Kento Nakajima) is a sex therapist at his own clinic, spending his days helping patients work through deeply personal, often unspoken struggles they can’t bring up with anyone else in their lives. He’s compassionate, skilled, and sincere with every client — but the show’s real hook is the contrast underneath: Ichito is quietly wrestling with his own psychological hang-ups around intimacy and connection, ones he’s never been able to resolve for himself. The series unfolds as a slow character study, following individual patient stories week to week while gradually peeling back the layers of Ichito’s own past and fears, especially once a spark reignites with Yumi (Yuko Araki), an old classmate he unexpectedly runs into.
Highlights
- Kento Nakajima’s lead performance anchors the show, marking his second major Netflix project and a notable dramatic showcase after his idol-group background with Sexy Zone.
- A genuinely mature, thoughtful approach to its subject matter — rather than being exploitative, the show treats its patients’ intimate struggles with real sincerity and emotional weight.
- A tight, focused format — at just 7 episodes, the series doesn’t overstay its welcome, keeping its character study concise.
- Strong source material — adapted from Kisei Tada’s manga, giving the show a well-defined narrative foundation rather than an original, untested concept.
- A slow-burn romantic thread with Yumi that develops alongside the therapy-of-the-week structure, giving the show real emotional throughlines beyond its individual patient stories.
Critical Reception
S&X holds a 4/5 rating on Rotten Tomatoes, with critics praising the show for turning what could easily have been a gimmicky premise into something genuinely thoughtful. One review summarized it as a show that “turns an unusual premise into a thoughtful exploration of relationships, vulnerability and human connection, with Kento Nakajima delivering a nuanced performance.” Multiple critics have specifically noted the show avoids sensationalizing its subject matter — one MyDramaList reviewer with a professional counseling background wrote they’d initially worried the series would “hype up the sensationalism and make a mockery” of the therapy profession, but came away impressed by the “intelligence, respect, honesty, sensitivity, and warmth” of Nakajima’s performance and the production as a whole.
Several reviews draw an inevitable comparison to Sex Education, but note the shows land differently: where Sex Education leans into comedy and teachable moments, S&X stays focused on the emotional interiority behind its characters’ actions, prioritizing quiet character study over lessons or punchlines. Fan reviews have singled out the slow-burn romantic development between Ichito and Yumi as a particular highlight, praising how naturally their relationship unfolds rather than feeling rushed, alongside strong supporting chemistry from clinic colleagues Yuta (Ryota Miura) and Marin (Sawako Fujima), whose lighter banter balances out the show’s heavier emotional material.
Pros & Cons
Pros
- Handles a genuinely difficult, rarely depicted subject (sex therapy and intimacy issues) with sincerity rather than shock value.
- Nakajima’s performance is compelling enough to carry both the episodic patient stories and the deeper personal arc.
- A manageable 7-episode format makes it an easy, focused watch rather than a sprawling multi-season commitment.
- Strong early critical reception, holding a 4/5 score on Rotten Tomatoes alongside a solid 7.7/10 on MyDramaList shortly after release.
- Tackles taboo, rarely-explored themes (sexual anxiety, mental illness, intimacy struggles) with apparent care, according to its tagging and early reviews.
Cons
- The TV-MA rating and mature subject matter mean it’s decidedly not for all audiences or casual viewing situations.
- As a newly released show, its user rating is based on a relatively small sample size (under 500 users at time of writing), so reception may shift.
- Being a niche, mature-themed J-drama, it may have limited crossover appeal outside audiences already interested in intimacy-focused character dramas.
- Some viewers searching for it expecting a K-drama (a common mix-up given its title and Netflix placement) may be surprised by its Japanese origin and tone.

Final Verdict
S&X is a quietly ambitious character study that treats a rarely-depicted subject — sex therapy and intimacy struggles — with real sincerity rather than shock value, anchored by a strong central performance from Kento Nakajima. Its tight 7-episode format and mature, thoughtful tone make it a notable, if niche, addition to Netflix’s Japanese drama catalog, even if its very title continues to cause some understandable confusion with the K-drama genre.
Rating: 7.5/10 — A sincere, well-acted character drama that handles difficult subject matter with genuine care.
