Taeyeon is often regarded as the "idol of idols" in the industry and her star-studded concert guest lineup proves why. 

Taeyeon's 5th solo concert 'The ODD Of LOVE' was held on June 3 and 4 KST at KSPO DOME at Seoul Olympic Park. Tickets to her show sold out immediately during the pre-sale period and because it was her first solo concert in about 3 years and 5 months since 'THE UNSEEN' in January 2020, many celebrities attended her concert. 

Seventeen's Seungkwan, Vernon, Dino, and Hoshi, all LE SSERAFIM members, IVE's Yujin, Leeseo, Liz, and Gaeul, Kim Jae Joong, Baek Ah Yeon, Zior Park, aespa's Karina and Winter, Super Junior's Donghae and Eunhyuk, NCT's Doyoung, SHINee's Minho, Taemin, and Key, rapper Han Hae, Sunday, Yeon Woo, Son Na Eun, Jeong Ye In, actor Ahn Bo Hyun, singer Juniel, singer HYNN, and more. Of course, Girls' Generation members Seohyun, YoonA, Tiffany Young, Sooyoung, and Hyoyeon were there as well to show support for Taeyeon.  

Fans commented: "Red Velvet would have been there if it were not for their world tour."

"I didn't know Kim Jae Joong was still friends with Taeyeon."

"4th gen girl groups IVE, aespa, and LE SSERAFIM all went to Taeyeon's concert. No wonder Taeyeon is an idol of idols." 

"It's so funny to me that Doyoung went there with glasses and mask on lol Other celebrities seemed like they kinda expected to be recognized but not him."

"Taeyeon is legendary..."
