TWICE's Sisterhood: Who Is Nayeon Best Friend in TWICE?

The Unbreakable Bond: Nayeon and Jeongyeon's Trainee Story

Before the roaring crowds and stadium lights, there were the stark white practice rooms of JYP Entertainment. It's here that the deepest bonds in K-pop are often forged, and for TWICE, this is especially true. So when you ask who is Nayeon best friend in TWICE, the story almost always begins with Yoo Jeongyeon. Their friendship is the stuff of legend among ONCEs (the official name for TWICE's fanbase), a foundational relationship that has weathered trainee struggles, the intense pressure of a survival show, and the whirlwind of global stardom.

Nayeon and Jeongyeon, often affectionately dubbed "2yeon" by fans, joined JYP Entertainment around the same time in 2010. For five long years before their debut, they were inseparable. They navigated the demanding trainee system together, sharing meals, dreams, and the anxieties of an uncertain future. This shared history created a unique, almost familial understanding between them. You can see it in the way they interact, a comfortable shorthand built on a decade of mutual support. They are often called the 'parents' of the group, with Jeongyeon's steady, caring nature balancing Nayeon's bright, energetic leadership as the eldest member.

This bond was put to the test during the Mnet survival show "SIXTEEN" in 2015, the very show that formed TWICE. The format pitted trainees against each other, yet Nayeon and Jeongyeon's support for one another never wavered. This loyalty in the face of competition solidified their status as a core duo within the future group. Today, you can still see that deep connection in their variety show appearances like "Time to Twice." They bicker like sisters, laugh until they cry, and instinctively look to each other in chaotic moments. It’s a friendship that doesn't need performative gestures, it's lived-in, authentic, and a cornerstone of TWICE's group dynamic, much like Sana's unique friendship dynamics add another layer to the group's chemistry.

A Different Chemistry: Nayeon and Momo's Playful Dynamic

While Jeongyeon represents a deep, sisterly bond with Nayeon, her friendship with Momo Hirai showcases a completely different, yet equally important, dynamic. If 2yeon is the steady heartbeat of the group, the Nayeon and Momo pairing, or "Namo," is the spontaneous burst of laughter. Their friendship is built on a foundation of playful teasing, shared humor, and an undeniable affection that lights up any room they're in. For years, they were roommates, a situation that only amplified their chaotic and hilarious energy.

Fans adore their interactions on V LIVE broadcasts and behind-the-scenes footage. Nayeon, despite being the oldest, often lets her guard down around Momo, engaging in silly antics and inside jokes. Momo's sweet and sometimes slightly clueless persona brings out a mischievous, teasing side of Nayeon. They share a love for food, especially jokbal (pig's trotters), a fact that has become a running gag within the fandom. Their dynamic is a perfect example of how different personalities can complement each other to create a fun and supportive environment. Nayeon is the quick-witted talker, while Momo is the master of dance and hilarious reactions. Together, they are pure entertainment.

Their closeness is also physical and unabashedly affectionate. They are frequently seen hugging, leaning on each other, and sharing moments of casual intimacy that speak volumes about their comfort level. This isn't just for the cameras. It's a genuine reflection of a friendship where both feel completely at ease. Momo, who moved from Japan to pursue her dream, found a welcoming and loving older sister figure in Nayeon. In turn, Nayeon found a friend who reminds her to embrace the sillier, more carefree moments in life. This balance is crucial for surviving the high-pressure world of K-pop, and their relationship is a testament to finding joy and laughter with the people around you.

The 'Unnie' Connection: Nayeon's Role as the Eldest

To fully understand Nayeon's friendships, you have to understand her role as the mad-unnie of TWICE. In Korean culture, "unnie" (언니) is what a younger female calls an older female friend or sister. As the oldest member of the group, Nayeon is the unnie to eight other members, a position that comes with an unspoken set of responsibilities. She's not just a friend, she's a leader, a mentor, and a pillar of support for the younger members, especially the 'maknae line' which consists of Dahyun, Chaeyoung, and Tzuyu.

Her relationship with each member is tailored to their personality. With Dahyun, she shares a bright, almost hyperactive energy. They are often the loudest and most energetic duo, leading the charge in variety show games. With Chaeyoung, the group's main rapper and resident artist, Nayeon takes on a more nurturing role, constantly praising her creativity and encouraging her artistic pursuits. And with Tzuyu, the youngest and often shyest member, Nayeon is fiercely protective, making sure she feels included and comfortable, often initiating hugs and encouraging her to speak up.

This role of the reliable older sister doesn't mean the relationship is one-sided. The younger members, in turn, provide Nayeon with immense energy and keep her grounded. They look up to her, but they also aren't afraid to tease her, which keeps the group's dynamic refreshingly balanced and prevents a rigid hierarchy. This dynamic is a common thread in many successful K-pop groups, where the age-based roles foster a family-like structure. Observing how Jisoo from BLACKPINK navigates her role as the eldest in her group provides an interesting parallel to Nayeon's own leadership style. Ultimately, Nayeon's position as the unnie means her best friend isn't just one person, it's a role she plays for everyone, adapting her support and affection for each of her eight 'younger sisters'.

Beyond the Stage: How TWICE's Friendships Shape Their Music

The genuine sisterhood within TWICE isn't just heartwarming fan service, it's the secret ingredient to their incredible success and longevity. This authentic chemistry translates directly into their work, elevating their music, performances, and overall appeal. When you see TWICE on stage, you're not just watching nine talented individuals, you're watching a single, cohesive unit that moves and breathes together. Their synchronization, a hallmark of K-pop, is born not just from endless hours of practice, but from a deep, non-verbal understanding of one another.

This synergy is especially evident in their more emotionally charged songs. Take their 2019 hit "Feel Special." The lyrics, penned by JYP Entertainment founder J.Y. Park after he had conversations with the members about their struggles, speak of finding light in a dark world through the presence of a loved one. When TWICE performs this song, the emotion is palpable because they are singing it to, and for, each other. The reassuring glances, the supportive hand on a shoulder, the shared smiles, it all stems from a real place. Their bond gives the song's message an unshakable authenticity that resonates deeply with listeners.

This closeness also fosters a safe and creative environment behind the scenes. Members are increasingly involved in songwriting, and they often draw inspiration from their shared experiences. This collaborative spirit allows them to create music that is personal and relatable. Because they trust each other implicitly, they are not afraid to be vulnerable, to experiment with new concepts, or to give each other constructive feedback. This trust is the reason they were all able to unanimously decide to renew their contracts with JYP Entertainment in 2022, a rare feat in the K-pop industry. Their friendship isn't just part of the job, it's the foundation upon which their entire empire is built.

Nayeon's Solo Style: How Her Friends Influence Her Look

Nayeon is a certified style icon, known for her fresh, peachy, and effortlessly chic aesthetic. Her look perfectly embodies the 'pop' in her solo music, but like any trendsetter, she draws inspiration from the world around her, including her closest friends. The members of TWICE have distinct personal styles, and their constant proximity allows for a beautiful exchange of ideas, whether it's borrowing a lip tint or offering an opinion on a stage outfit. This collaborative beauty environment helps each member refine their signature look.

Nayeon's signature makeup often revolves around a flawless, radiant base and a vibrant, juicy lip. To achieve that K-beauty 'glass skin' effect, a high-coverage yet lightweight cushion foundation is essential. Products like the TIRTIR Mask Fit Red Cushion or the Hera Black Cushion are perfect for creating that smooth canvas. For her iconic lips, she often leans towards glossy tints that provide both color and shine. Think of the viral Amuse Dew Tint in a soft coral shade or the beloved Romand Juicy Lasting Tints. These products give her that plump, 'just-bitten' look that has become synonymous with her style.

While Nayeon has her go-to look, you can see subtle influences from her members. Momo's edgier, performance-focused style might inspire Nayeon to try a bolder eyeliner for a special stage. Sana's perpetually cute and feminine vibe might encourage her to add extra blush, perhaps using a cream product like the FWEE Lip & Cheek Blurry Pudding Pot for a natural flush. Even Jennie from BLACKPINK's iconic style, known for its high-fashion 'Chanel' chic, sets a benchmark in the industry that inspires all idols to experiment. The TWICE dressing room is a creative hub where these influences are shared freely, allowing Nayeon to constantly evolve her look while staying true to her bright, peachy core.

More Than Just Members: A Look at the Entire Group's Sisterhood

So, after exploring her foundational bond with Jeongyeon and her playful dynamic with Momo, who is Nayeon's best friend in TWICE? The most accurate answer is that she doesn't have just one. The real magic of TWICE lies in the intricate and powerful web of friendships that connects all nine members. To single out one relationship would be to miss the bigger picture: TWICE operates as a family. Each member plays a unique role, and each friendship offers Nayeon something different. Jihyo, the group's powerful leader, is her confidante and a fellow pillar of strength. Mina is a source of calm and quiet understanding. The younger members keep her spirit youthful and energetic.

This collective bond is what has enabled TWICE to navigate nearly a decade in a notoriously tough industry without losing a single member. Their decision to renew their contracts together in 2022 was a powerful statement to the industry and their fans. It declared that the entity of TWICE, the nine of them together, was more important than individual pursuits. This level of unity is exceedingly rare and speaks volumes about the health and authenticity of their relationships. They actively choose to be together, not just as colleagues, but as a chosen family.

You can see this in their unscripted content. They vacation together, celebrate birthdays with genuine enthusiasm, and support each other's solo projects with the passion of true fans. When Nayeon released her solo album "IM NAYEON," the members were her loudest cheerleaders. This unwavering support system is the key to their individual and collective success. Therefore, the concept of a single "best friend" feels too limiting for a group like TWICE. Nayeon is at the center of a constellation of nine stars, and each one shines brightly on its own while contributing to the brilliance of the whole.
