Donggyu
Donggyu (동규) is the leader of TUNEXX, IST Entertainment's 7-member boy group that debuted on March 3, 2026 with the mini album SET BY US ONLY. Born Park Dong-gyu (박동규) on March 16, 2005 in Ansan, Gyeonggi-do, he is the oldest member of the group and the one who set its tone from day one.
Standing at 182 cm, Donggyu brings a commanding stage presence to TUNEXX as its main vocalist. He is INTP in MBTI, a personality type reflected in his thoughtful, detail-oriented approach to music and performance. Before TUNEXX, he was a trainee at Pledis Entertainment, building a pre-debut profile that also included a strong showing on Boys II Planet (2025), where he consistently ranked among the top contestants.
Donggyu studied at Hanlim Multi Art School, the well-known performing arts high school that has produced a long list of K-Pop talents. He was among the first members officially announced for the new IST group in late 2025, alongside fellow Boys II Planet alums.
As leader, Donggyu has spoken about wanting TUNEXX to connect with fans through sincerity -- not just performance. The group's debut title track Proof That I'm Alive showcases exactly that: a declaration of identity and presence that he helped shape with the rest of the lineup.
