Hearts2Hearts earn praise for razor sharp synchronization in first 'RUDE!' live stage

Netizens are impressed by Hearts2Hearts' synchronized choreography for "RUDE!"

On an online forum, netizens reacted to several fan taken videos of the SM Entertainment rookie girl group performing their first live stages of their latest song, "RUDE!" Many highlighted the sharp, 'knife-like' synchronization of the choreography, with every movement perfectly aligned.

좋다... 단순히 동작의 통일성을 넘어서 힘조절하는 농도까지 다같이 맞춰져 잇을 때만 나올 수잇는 이 일체감, 철저하게 설계된 티. 가 좋다 루드 입덕 어 너네 진짜 잘해 https://t.co/LdiIXPh3Dn pic.twitter.com/uv4ozDXmYa

While many K pop groups are known for highly synchronized routines, netizens applauded the girl group for matching each other's "power and energy" with controlled, unified movements, often saying the performance reminded them of the heyday of Girls' Generation.

They were also impressed by the song's catchiness alongside the choreography, leaving comments such as: "'RUDE!', this is the one," "This is so good... Beyond just synchronized movements, this sense of unity that can only come when even the intensity and control of their power are perfectly matched together, you can tell it’s thoroughly designed. I love it. Rude made me become a fan. Wow, you guys are seriously so good," and "The song is so good. The perfectly sharp, synchronized choreography is seriously so satisfying lol."

On stage, Hearts2Hearts wore matching sporty tennis dresses paired with pink sneakers, creating a cohesive team look. Meanwhile, the group will begin official promotions for the new song this upcoming week, heightening anticipation for their comeback activities.
