In a refreshing departure from standard entertainment agency press releases, singer-turned-actress Ki Huihyeon (formerly of the girl group DIA) and popular model Lee Sangyoon have personally announced that they are in a romantic relationship.
The couple opted to share their happy news directly with their fans via social media, utilizing a charmingly unique piece of footage gathered during a romantic getaway to Osaka, Japan.
The unexpected yet highly affectionate public disclosure has rapidly captured the attention of netizen communities and entertainment media outlets alike, drawing widespread praise for its creative and candid nature.
On June 23, 2026, Ki Huihyeon sent shockwaves of excitement through her personal Instagram account by posting a brief video clip documenting her recent travels.
Rather than a carefully staged couple photo or a professionally shot vlog snippet, the shared video consisted of street-level closed-circuit television (CCTV) screen footage found along the streets of Osaka.
The video openly captured the two walking closely together, hand in hand, looking like any other joyful couple enjoying an overseas vacation.
Upon spotting themselves on the public monitoring display, the pair paused, checked the feed in real-time on their smartphones, and beamed brightly while waving their hands directly at the camera lens in a playful, coordinated gesture.
Revealing the Romance Through Playful Social Media Captions
The creative nature of the reveal was further amplified by the sweet interactions left in the post’s text and comment sections.
Huihyeon chose not to hide her companion’s identity, directly tagging Lee Sangyoon’s official profile handle within the post itself.
Commemorating the trip and the quirky manner in which they chose to showcase their bond, she accompanied the video with a lighthearted, sentimental caption, stating:
“Creating memories with CCTV in Osaka for the first time.”
The romantic atmosphere instantly heightened when Lee Sangyoon noticed the tag and wasted no time reciprocated the public display of affection.
He pinned a short but deeply meaningful response under the video, typing out a sweet statement that effectively cemented their status as an official couple:
“I was happy.”
Following this initial interaction, eagle-eyed fans quickly realized that the duo had been subtly leaving a trail of “lovestagram” clues prior to the formal declaration.
Netizens revisited their past social media timelines to find that the couple had frequently visited identical vacation spots and cafes in Japan.
In several of Sangyoon’s previously posted photos, small but unmistakable details—such as the edge of Huihyeon’s favorite handbag, her distinctive footwear, and matching scenic backdrops- were subtly captured in the frame.
This realization led many fans to comment that they had already suspected the romance blooming behind the scenes, celebrating the fact that the couple no longer feels the need to conceal their beautiful partnership.
A Look at the Couple’s Diverse Backgrounds in the Entertainment Industry
The pairing brings together two prominent figures from different corners of the South Korean entertainment industry, each possessing a distinct career trajectory that has endeared them to the public.
Born in 1995, Ki Huihyeon initially rose to prominence within the K-pop landscape, making her official debut in 2015 as the charismatic leader and main rapper of JYP Entertainment’s contemporary peers, the girl group DIA (DIAMOND).
She solidified her individual fanbase the following year by participating as a highly competitive contestant on Mnet’s landmark survival reality series, Produce 101 Season 1, where she ultimately finished in an impressive 19th place.
Following the conclusion of DIA’s group activities in 2022, Huihyeon successfully transitioned into acting, showcasing her versatility across various mediums, including web dramas like Love in Black Hole and Love and Wish, the theatrical play Yeodo, and her current creative projects.
On the other hand, Lee Sangyoon has carved out a successful path as a sought-after fashion model with a fascinating background as a former baseball player.
He transitioned into mainstream household recognition last year after appearing on Channel A’s hit dating reality variety program, Heart Pairing.
Stepping onto the show midway through as a formidable “Megi-nam” (a term used for late-arrival male contestants brought in to stir up competitive tension), his striking physical proportions, athletic background, and effortless charm quickly placed him at the center of a dramatic love triangle.
While Sangyoon had faced unverified online dating rumors during the broadcast of Heart Pairing- all of which he firmly denied at the time as baseless false information- this current open announcement alongside Huihyeon carries an entirely different, incredibly confident energy.
Fans and well-wishers worldwide have flooded both of their personal accounts with warm messages of support, expressing admiration for how naturally and confidently they have embraced their love.
