A small controversy started in the Hearts2Hearts fandom after new teaser photos for the group's upcoming comeback, Lemon Tang, were released. Some fans became unhappy with the way member Carmen was styled in the photos and decided to protest.

The new Lemon Tang concept photos showed the members enjoying a beach theme with bright colors and large lemon decorations. Fans quickly noticed that Carmen was the only member wearing long pants, while the other members wore shorts and lighter beach outfits.

Some fans felt that this styling choice was unfair. They believed Carmen's outfit did not match the beach concept and made her stand out from the rest of the group. Fans also claimed that Carmen received less attention in the teaser photos compared to other members.

To show their frustration, some fans sent protest trucks to SM Entertainment's headquarters. The trucks displayed messages asking the company to treat Carmen fairly. Fans requested equal styling, camera time, singing parts, and stage time during the group's comeback promotions.

Supporters of Carmen also pointed out that she comes from Bali, Indonesia, and felt that her outfit did not fit the beach theme. Some fans even edited the photos online to show how Carmen might have looked wearing shorts instead of long pants.

However, not everyone agreed with the protest. Some netizens felt that the issue was not serious and believed the reaction was too extreme.

The situation has divided Hearts2Hearts fans. While some believe Carmen was treated unfairly, others think the protests were unnecessary. As the group's comeback approaches, fans continue to discuss the issue online.
