Jiwoo is already capturing attention as a member of SM Entertainment's highly anticipated new girl group, Hearts2Hearts.

On online forums, netizens are actively discussing Hearts2Hearts, whose concept and lineup were introduced through a VCR video during 'SMTOWN LIVE 2025.' The group consists of eight members, led by Jiwoo, who was born in 2006.

Hearts2Hearts features a diverse lineup with members from Thai, Indonesian, and Chinese backgrounds, along with Korean members.

Among them, Jiwoo stands out with her impressive height of approximately 170cm and her flexible physique, attributed to her background as a ballet dancer. Her short bob haircut further highlights her distinct presence in the VCR and in candid airport photos captured by fans.

Netizens were particularly impressed by her proportions, striking visuals, and long history as a trainee. Jiwoo joined SM Entertainment while still in the 6th grade, showcasing her dedication and early start in the industry. Many have even compared her to STAYC's Isa, noting their similar visuals.

More reactions include:

"Why does this baby have such long legs?"

"Wow, seriously an idol."

"Wow, I thought she was (STAYC's) Isa for a second."

"Wow, but she’s so pretty."

"She’s a bias-wrecker."

"Jiwoo… I think… I’m going to start getting to know you now. You’re so, so pretty. Seriously, this baby is posing so professionally for her profile photos. So proud."

"They say she has an innocent vibe, but she’s also talented. SM must not have wanted to let her go—a visual and skill member."

"Wow, look at how crazy long her arms and legs are."

"Wow, ballet. She must be really flexible."

"But Jiwoo has always been a well-known trainee… lol, it feels like she’s been doing this for a long time."

"Wow, she’s young but has been at it for so long. Amazing."

"She looks like Isa."

Alongside the teaser trailer for Hearts2Hearts revealed at the SMTOWN concert, the names of the group’s members have been circulating online: Serisa, Carmen, Jiwoo, Haram, Jooeun, Yoona (real name Dahyun Stella Kim), Ian, and Nayeon. The members’ birth years are estimated to range from 2005 to 2010.
