In the latest trailer for the upcoming show "Apartment 404," BLACKPINK's Jennie left netizens in stitches with an unexpected and adorable interaction featuring TXT's Yeonjun. Both idols, known for their exceptional visuals, talent, and charm, have garnered massive fan followings as representatives of the third and fourth generations of K-pop idols, respectively.

Jennie, who has earned the title of "third-generation IT girl," showcased her charm as a member of the cast in a scene that took an amusing turn. In the snippet, the idol had netizens LOLing when she started to swear, only to abruptly stop herself with a cute and unexpected reaction.

What caught the attention of fans even more was the immediate cut to the reactions of the cast, including TXT's Yeonjun. In the clip, Yeonjun couldn't contain his laughter at Jennie's hilariously relatable moment. Although not confirmed as a full-time cast member, it appears that Yeonjun might be making a cameo appearance on the show.

The unexpected interaction between the two idols has sparked a wave of excitement among fans. Some netizens couldn't get over the humorous exchange, while others joked that some fans initially believed Yeonjun was reacting to Jennie's aegyo rather than her near-swearing incident.

This isn't the first time fans have been treated to interactions between Jennie and TXT. In November, both idols attended the W Korea "Love Your W" event, sitting next to each other and sending fans into a frenzy.

As anticipation builds for the release of the full episode, fans are expressing their hopes for more delightful interactions between Jennie and Yeonjun. Whether it's on-screen chemistry or off-screen camaraderie, it seems like this unexpected pairing is winning hearts across the K-pop community.
