Ep. 1: Paanch Sawaal (2025-09-30)

Ritesh, a sharp and successful venture capitalist, is sent to Jaipur by his firm to pitch a nationwide expansion plan to MT Sir, a legendary yet low-profile IIT JEE coach. But this meeting stirs up more than business-it reopens a chapter from Ritesh's own past, where a single mark and a simple challenge from MT Sir had changed everything. As old memories resurface and new ambitions collide, Ritesh is forced to confront not just the intent behind this potential investment but a deeper question: what truly defines success? The past and present intertwine, setting the stage for a decision that could reshape both their lives.
Ep. 2: Kuch Bhi Ho Sakta Hai (2025-09-30)

With his corporate ties cut, Ritesh dives headfirst into building something meaningful with MT Sir-but not everyone shares their vision. A tense investor meeting tests their commitment to authenticity in a world obsessed with optics. Meanwhile, flashbacks to Ritesh's time in Kota reveal an intense rivalry, mounting pressure, and a crucial lesson about speed versus intelligence. As the academic battlefield heats up and personal struggles deepen, a beautiful new connection offers Ritesh solace. But just as he finds his footing, a sudden shift threatens to upend everything he believed about success. Some lessons arrive too late-and hit the hardest.
Ep. 3: Cheating (2025-09-30)

Ritesh finds himself torn-between loyalty and logic, passion and practicality, as MT Sir enters an entrepreneurship competition without consulting him. Ritesh is skeptical; the prize feels too small, the odds too big. But for MT Sir, it's a matter of belief, not scale. Flashbacks reveal a younger Ritesh, thrown off course by sudden changes in the JEE pattern, losing focus just as his connection with Sheena deepens. In the present, Ritesh's ego gets battered when he learns that an old colleague will be judging the competition. With a crucial decision looming, Ritesh stands at a breaking point. As echoes of the past return, will he succumb to his own demons?
Ep. 4: The Clock Is Ticking (2025-09-30)

As the E-Summit nears, cracks begin to show-both in the present and the past. Ritesh wrestles with a decision that could impact MT Sir's moment in the spotlight, while memories of youthful jealousy and failure resurface. A tangled past with Sheena and a bitter rivalry with Abhishek reveal the emotional toll of ambition. In the present, even MT Sir isn't immune to pressure, questioning his place among slick-talking entrepreneurs. As doubts creep in and fears resurface, the story draws powerful parallels between past breakdowns and present reckonings-testing how far each man is willing to go to rise again.
Ep. 5: Handshake (2025-09-30)

Defeated by doubt, MT Sir returns from the E-Summit-but a new investment opportunity reignites hope. As he and Ritesh prepare for a fresh pitch, whispers from the past return: a younger Ritesh spiraling after a major debacle, only to be pulled back from the edge by MT Sir's wisdom. As past failures slowly transform into lessons of humility and focus, the present challenges begin to mirror them. With an unexpected second chance knocking, both mentor and mentee must decide-will they let fear dictate the future, or rise above it? Sometimes, the bravest move is just showing up.
