A first-day post from the sets, a director's name tagged with a sense of ceremony, and a quietly emotional line about seven years — that's how the cameras started rolling on Mismatched Season 4, the final chapter of Netflix's long-running campus romance.
There's a particular kind of post that actors put out when a show is ending — not a teaser, not a trailer, just a quiet acknowledgment that something is closing. That's what Rannvijay Singha shared on the first day of shooting for Mismatched Season 4, the finale season of the Prajakta Koli and Rohit Saraf-led Netflix series. The behind-the-scenes pictures themselves were fairly ordinary — a set, a chair, a costume rack — but the caption carried the weight of seven years spent inside one character: Professor Siddharth Sinha, better known to the show's audience simply as Sid.
What Happened on Day One of the Mismatched Season 4 Shoot
Rannvijay Singha posted a set of behind-the-scenes photographs marking the start of principal photography for Mismatched Season 4. In his caption, he reflected on having played the role of Sid for roughly seven years, calling himself grateful for the character, and said the team was committed to giving the story "the ending that it deserves." He also welcomed Divyang Thakkar, who is directing this season, referring to him as the "captain" for the final outing.
What makes this post noteworthy isn't the content of the image — fans have seen plenty of set photos over four seasons — but the framing. It reads less like a promotional update and more like a personal note, the kind an actor writes when they know the cameras rolling on day one are also, eventually, going to roll for the last time on this particular character.

Why It Matters: Seven Years of Professor Sid
To understand why this first-day post resonates, it helps to look at the timeline. Mismatched first premiered on Netflix in 2020, based on Sandhya Menon's young-adult novel When Dimple Met Rishi, adapted and relocated to Jaipur by creator Gazal Dhaliwal. Rannvijay Singha's Professor Sid was introduced as the sharp-tongued but secretly soft-hearted faculty member overseeing the show's central app-building competition — a role that has run across all three previous seasons.
For an actor known primarily for his years hosting Roadies, the Mismatched run has quietly become one of his longest scripted commitments. Seven years — from a 2020 debut season to a 2026 finale shoot — is a long time to inhabit one character, especially a supporting one whose arc (his relationship with Vidya Malvade's Zeenat Karim) has simmered in the background of the show's louder teen romances.

The Bigger Picture: Mismatched Season 4 as Netflix India's 2026 Finale Event
The announcement of Mismatched Season 4 came in February 2026, when Netflix India revealed it as part of a larger 2026 slate that also included titles such as Maa Behen, Lust Stories 3 and Mamla Legal Hai 2. Rather than a conventional first-look poster, the makers released a short teaser revisiting Rishi and Dimple's relationship — from their first meeting to the moment Dimple called off their engagement at Marine Drive in the Season 3 finale.
That ending left several threads open, not just for the show's central couple but for the supporting cast as well. Sid and Zeenat's relationship, Anmol and Vinny's dynamic, and Celina and Krish's storyline were all left without resolution — and Season 4 has been positioned by the makers as the season that ties up these arcs for good.
Why a Supporting Character's First-Day Post Matters to the Show's Audience
It's easy to dismiss a single Instagram caption as routine promotion. But for a show built on ensemble chemistry — where even minor characters like Sid and Zeenat have devoted fan followings — these small, personal posts often function as the first real signal of a season's tone. Rannvijay Singha's choice to frame his post around gratitude and closure, rather than excitement about a comeback, suggests the final season is being approached by its cast as an emotional send-off rather than just another production cycle.
Cast and Crew Returning for the Final Season
The ensemble nature of Mismatched has always been one of its strengths, and Season 4 brings back nearly the entire familiar cast for the show's closing chapter.

Behind the camera, Divyang Thakkar takes over directing duties for the finale season — a notable handover, since previous seasons were directed by Nidhi Bisht (Season 1) and Akarsh Khurana (Season 2 and 3). The show continues to be created by Gazal Dhaliwal and produced by Ronnie Screwvala's RSVP, the production house behind the franchise since its inception.
What Happens Next: Release Timeline and What to Watch For
As of now, Netflix has not confirmed an official release date for Mismatched Season 4. With filming having started only this week, a realistic premiere window — based on the production timelines of the previous seasons — would likely fall in the latter half of 2026, though this remains an estimate rather than a confirmed date.
For viewers, the key things to track over the coming months will be:
- Official confirmation of a release window from Netflix India once principal photography wraps
- Whether Sid and Zeenat's relationship gets a definitive resolution, as hinted by early reports
- How the new director's approach shapes the tone of the finale compared to earlier seasons
- Any further cast updates as filming progresses through 2026
For a show that began as a lighthearted campus romance in 2020, the fact that its finale season is opening with a cast member's personal reflection on gratitude says something about how Mismatched has positioned its ending — not as a victory lap, but as a goodbye to characters that have, in Rannvijay Singha's words, been "lived" for years.
