Fans of Red Velvet's Yeri defended her friendship with Pentagon's Hongseok.

On June 25, the topic of Yeri's male friends trended on Nate's online community site Pann. One netizens posted the photos below along with the title, "Yeri has a lot of male friends."

Other netizens and fans of Yeri did not respond positively to the post as they commented, "They got close while they filmed a drama, so what do you want from them? Are you jealous she has a lot of male friends? Yeri doesn't just have a lot of male friends, she has a lot of female friends too," "They're not close. They just took the photos to promote their drama," "They came out in a drama together. What do you want from them," and more.

Yeri and Hongseok are starring in the new web series 'Blue Birthday', which is set to premiere on Naver TV on July 23 KST and YouTube on August 6 KST.
