Training that began outside a school
Yuha (유하) was the first of the Hearts2Hearts members to begin life as a trainee. When the group appeared on MBC FM4U’s Good Morning, Yoon Sang (오늘 아침 윤상입니다) in October 2025, she said she had been scouted outside her school when she was in the fourth grade of primary school, and looked back: “My first evaluation song was ‘Yeouya’ by our senior Joy. Singing that song, I became really interested and felt that performing on stage was fun” (Newsen).
Of the long training period she said at the debut showcase, “During my long life as a trainee there were of course hard moments, but it was a rewarding time in which I worked to achieve the dream I wanted” (Pickcon). At the same event she introduced the title track of the first single The Chase as “a song with an appealing mysterious, dreamlike mood. You can feel a variety of moods within a single song” (The Korea Economic Daily).
In the host’s seat
Her first hosting job was MBC’s Show! Music Core on 4 October 2025. Hearts2Hearts hosted that day as a group, and My Daily described the broadcast as the first hosting attempt for six of the members, Yuha among them. On 26 February 2026, on Mnet’s M Countdown, where the group gave the first performance of its new song RUDE!, she was a special MC with Ian and Jiwoo (Newsen), and on 7 March, for episode 937 of Show! Music Core, she filled in alone as special MC when TWS’s Dohoon was away on an overseas schedule (Topstar News).
Songs and campaigns
On 15 June 2026 the production company SAMG Entertainment announced that Yuha and Jaehee of NCT WISH would sing ‘눈을 떠봐’ (Nuneul Tteobwa), the first special OST for the animated feature 사랑의 하츄핑: 고래보석의 전설 (Sarang-ui Hachyuping: Gorae Boseok-ui Jeonseol) (Kyeonggi Ilbo). bnt News reported that the collaboration was part of a strategic partnership agreement SAMG and SM had signed the previous year. Music director Kim Tae-ho, who has worked on the Teenieping series, took part in the duet, which was released on 1 July (Sports Donga), and the film opened on 5 August.
On 28 April she was appointed, with Stella, as a 2026 ambassador for M Clean, a campaign organised by the Maeil Business Newspaper and MBN — her second year, after serving with Jiwoo in 2025 (Maeil Business Newspaper). “I know well that fans have a lot of feelings and thoughts about even one short post we put up,” Yuha said, “so I think harder when I post things.” At the showcase for the second mini album Lemon Tang on 22 June she said of the title track, “From the moment I heard the demo, I felt summer right from the start” (Asia Economy).
