About 2Yeon

2Yeon (also written NaJeong) is the fan-shipped friendship pairing between TWICE's Im Nayeon and Yoo Jeongyeon, the group's two oldest members. Their shared seniority in TWICE, paired with contrasting personalities — Nayeon openly playful and affectionate, Jeongyeon cooler and more reserved on the surface — has made their dynamic a fan favorite since TWICE debuted in October 2015. Within TWICE's large fan community (ONCE), 2Yeon is one of the most recognized intra-group ships. Fans frequently highlight how Nayeon publicly initiates affection while Jeongyeon acts reluctant but ultimately reciprocates. This love-hate energy is a recurring motif in their TV appearances and fan-compiled content. A widely shared Instagram moment saw Jeongyeon post a photo of herself and Nayeon holding a card that read 'We registered our marriage!' — a lighthearted joke that delighted the fandom. Jeongyeon faced health challenges and took extended breaks from TWICE activities in 2021-2022, and the group's visible support during that period has added an emotional layer to their friendship that fans hold dear. When Nayeon made her solo debut in June 2022 as the first TWICE member to go solo, behind-the-scenes footage showed Jeongyeon, Jihyo, and Dahyun visiting the shoot set to cheer her on.

2Yeon is one of TWICE's flagship intra-group ships with over a decade of documented content. ONCE fans often highlight both the playful on-stage banter and the quieter moments of genuine care, making it one of the richer friendship ships in the fourth-generation/veteran era of K-pop fandom.
