The premiere of Season 4 of "Never Have I Ever" picks up right where we left off, amidst the afterglow of Devi and Ben's maiden sexual encounter at Ben's abode. Both adolescents are immersed in an uneasy silence until Ben abruptly announces his intentions to "hit the sack." He politely offers to summon a cab for Devi, but she decides to dress and depart solo, her heart heavy with unresolved emotions.
The following morning, Devi unburdens herself to Eleanor and Fabiola, detailing the sexual experience with Ben and confessing how disappointing it was for her. Assuming Ben shared her sentiments, she sends him a casual text, proposing a coffee rendezvous. Meanwhile, Ben, engrossed in his workout session at the gym, happens to cross paths with NBA legend Dwight Howard. Spontaneously, Ben opens up to Dwight about his sexual debut, admitting it was far from satisfactory.
Ben divulges that Devi hastily left after their intimate moment, prompting Dwight to advise that Ben should seek companionship with someone who reciprocates his desires for a relationship, rather than with Devi, who was clearly more invested in him. Responding to Devi's text, Ben cites his busy schedule and declines her meeting invitation.
As the summer months slip by unnoticed, Devi finds herself on the threshold of her senior year, heading to school with a prayer on her lips, hoping for a letter of recommendation from her esteemed AP Literature professor, Dr. Keyes, for Princeton admission. Outside their residence, Devi's mother, Nalini, gifts her an old car, empowering her to commute independently.
Elsewhere, Paxton, now a college student at ASU, finds himself nostalgic for high school amidst a conversation with Trent. In a moment of longing, Paxton agrees to host a college party at his dorm, but his roommate's dismissive attitude stings, leaving him disheartened. Back at school, Eleanor and Fabiola are optimistic that Devi's romantic life is poised for a positive transformation.
Devi is eagerly anticipating her college journey, counting down the days until the application process begins. However, her enthusiasm is slightly dampened by her lingering awkwardness around Ben, stemming from their summer encounter. As the trio takes note of the new senior clique of rebellious jocks who have overshadowed the traditional athletes, Ethan Morales stands out prominently, his charm having intensified over the summer break. Eleanor can't help but be captivated by his allure, while Trent attempts to seduce her with a proposition of a passionate make-out session near the bleachers. Eleanor, focused on the start of her senior year, politely declines, citing numerous school commitments.
Devi ventures into her AP Literature class under the guidance of Dr. Keyes, a seasoned educator who pens Letters of Recommendation sparingly due to her advanced age and severe arthritis. Renowned for her conservative values, Dr. Keyes disapproves of teenage provocation in dress and romance. To make a favorable impression, Devi arrives dressed impeccably in her kilt and bearing a thoughtful gift for the elderly educator. She humbly requests consideration for one of Dr. Keyes' precious recommendations. The teacher responds noncommittally, suggesting that it's a matter to be discussed in due course.
Emboldened by her newfound confidence, Devi decides to confront Ben about their unresolved issues. However, her resolve shatters when she discovers that Ben has been seeing Margot. A surge of anger washes over Devi as she confronts Ben in the bustling cafeteria, accusing him of mistreatment. Ben counters that he perceived their sexual encounter as a solitary experience, and was surprised by Devi's abrupt departure.
Their heated exchange catches the attention of Margot, who steps in to shield Ben. She reveals to Devi that Ben had disclosed their "one-time fling" to her, terming it a casual encounter. The conversation escalates into a bitter altercation, with Devi making references to Ben's private parts within the earshot of fellow students and, inadvertently, Dr. Keyes, who collapses in the hallway after overhearing Devi's shocking revelation, fainted by the graphic details.
Devi and Margot are summoned to Principal Grubbs' office, where the principal insists that Margot offer Devi a sincere apology for her hurtful remark about attacking her. Margot mutters a lukewarm apology and hastily exits the room. Meanwhile, Trent eavesdrops on a conversation between Fabiola and Eleanor, discovering that Eleanor has plans to attend Juilliard and eventually relocate to England to pursue her theatrical ambitions. This revelation fills Trent with apprehension, fearing that Eleanor might end their relationship.
At the Robotics Club initiation ceremony, Fabiola finds herself frustrated and outnumbered as the applicants are exclusively male, making her the sole female member of the tech team. After school, Devi dashes to her therapist's clinic, arriving just in time to unload her frustrations about Ben, Margot, and her chaotic personal situation. Dr. Ryan reassures Devi that there is nothing inherently wrong with her and labels Ben as naive for not wanting to be with her for her true self.
The therapist advises Devi to channel her anger onto paper rather than confronting Margot or Ben verbally, which could lead to further complications. Dr. Ryan also points out that directing her anger solely at Margot is unfeminist, emphasizing that Ben bears part of the blame. Following the therapist's advice, Devi pens down her potential insults aimed at Margot in her notebook, eventually letting go of her grievances.
Later that evening, Paxton feels excluded at a party, unable to connect with the popular crowd and longing for his old friends. The next day, Devi initiates a conversation with Margot, apologizing for the awkward tension between them stemming from Ben's situation. The two manage to resolve their issues through open dialogue. However, Margot stumbles upon Devi's list of mean thoughts about her, causing her to fly into a rage and call Devi an asshole.
Unfazed by Margot's outburst, Devi is whisked away by Eleanor to the break room, where Trent has summoned her urgently. In an emotional moment, Trent proposes to Eleanor, asking her to marry him. Eleanor gently declines, breaking up with Trent because they were both still too young for such a commitment. Trent gracefully accepts that Eleanor is out of his league and doesn't want to hinder her from pursuing her dreams if she's not ready for a lifelong commitment. Despite the heartbreak, Trent ends their relationship amicably and walks away.
Ben intercepts Devi in the parking lot, apologizing for not returning her calls. He confesses his sexual inexperience and admits that their first time together was equally unfulfilling for him. He claims that their competitive natures make them incompatible as a couple. Devi, though bummed out by his honesty, promises to be the girlfriend Ben desires. However, Ben remains convinced that their relationship is doomed. They part ways on a positive note, acknowledging their mutual respect.
As Devi approaches her car, she discovers it has been vandalized, with 'that bitch' spray-painted across it, leaving her stunned and angry as the episode concludes.
