BTS’ Jin and Red Velvet’s Wendy Send Fans Into a Frenzy With Sweet Onstage Chemistry at Goyang Solo Concert

BTS member Jin's solo concert in Goyang has become a hot topic among K-pop fans — not just for the music, but for his unexpectedly bashful demeanor around Red Velvet’s Wendy during their live duet performance.

The two idols performed Heart On The Window, their collaboration track from Jin’s solo album Happy, during the second day of Jin’s RUNSEOKJIN_EP.TOUR. Wendy’s surprise appearance at the June 29 concert left fans buzzing, but it was Jin’s reaction to her presence that truly stole the spotlight.

Jin's Shyness Sparks Speculation

While both artists delivered a heartfelt performance, fans quickly picked up on Jin’s noticeably shy behavior. Unlike his usual confident stage presence, Jin avoided eye contact, giggled nervously, and even sighed wistfully after Wendy exited the stage.

The soft “ba-bye” he whispered in what fans called “the most baby voice” only fueled speculation that he may have a crush on the Red Velvet star. Social media lit up with comments like, "Jin has a crush on Wendy, and we’re here for it!"

A Throwback to Their Past Collaboration

Referring to their joint performance in November 2024, Jin addressed a popular fan joke about the wide distance between him and Wendy on stage back then. “There was talk that we were standing too far apart,” he admitted, as Wendy playfully chimed in, saying even other BTS members could have fit between them.

Jin explained that this time, the concert’s stage director had marked spots to ensure they stood closer — a move fans now believe might have been intentional to reflect his admiration for Wendy.

Fans Decode the Moment

Comparing Jin's demeanor with Wendy to his interactions with other female artists — including soloist Yena, who performed on the first night — fans noted a distinct difference. Jin appeared far more relaxed around Yena, while his bashfulness with Wendy stood out.

Some fans even suggested members of Jin’s team might be aware of his possible admiration. One user on X (formerly Twitter) wrote, “Who was he smiling and sighing at? His director? I feel like someone knows he likes Wendy.”

This isn’t the first time fans have sensed a special rapport between the two — Jin had previously praised Wendy’s vocals during an appearance on her radio show, where he also appeared visibly flustered.

Conclusion

Whether it’s just friendly admiration or something more, Jin and Wendy’s onstage chemistry has given fans plenty to talk about. One thing’s for sure — their duet was not only musically stunning but also packed with moments fans won’t forget anytime soon.
