Chat-Shire was the third concert tour by IU. She toured four cities in South Korea: Seoul, Busan, Daegu and Gwangju. The tour began on November 21, 2015, with two dates in Seoul and finished on December 31.
On October 19, 2015, four days before the release of IU's fourth extended play, Chat-Shire, it was announced that the singer would hold her third concert tour Chat-Shire in support of the EP, and would not perform on music shows to focus on live performances and her health, which had been deteriorating due to hectic schedules. Starting in November, the tour four cities in South Korea: Seoul, Busan, Daegu and Gwangju. Tickets for the first two concerts in Seoul were put on sale on Interpark on October 26 and, according to Loen, sold out in one minute. Ticket sales for the concert in Busan started on October 29. On December 8, it was announced that IU would hold two additional encore concerts at Jamsil Students' Gymnasium in Seoul on December 30 and 31. Tickets were put on sale on Interpark on December 10. On December 31, Loen announced on Facebook that a limited edition photo book would be sold alongside ticket reservations. It would also be sold on Melon Shopping.
Despite its success, Chat-Shire became controversial when the Korean publisher of the novel My Sweet Orange Tree (1968), from which IU took inspiration for the b-side "Zezé", criticized IU's "sexual" interpretation of the five-year-old protagonist in the lyrics of the song and on the EP's cover artwork. The scandal started a heated debate in the Korean entertainment industry over freedom of interpretation. As the main producer of the EP, she was also criticized for illegally sampling Britney Spears' 2007 song "Gimme More" on a bonus track of the EP. As a result, many ticket reservations were allegedly cancelled.
The concert lasted circa two hours, during which IU performed 20 songs. The first half focused on dance songs, while in the second half IU presented her popular ballads. IU appeared on the stage as a "fairy tale protagonist" wearing a white dress and opened the show with "Shoes". Upon presenting "Zezé", she said "It's a song in the new album. It's a song I love unchangingly". The concert marked IU's first performance of "Twenty-Three", during which she wore a black crop top and hot pants. Commenting on the outfit, she said "I thought it was like Sailor Moon. Isn't it like the clothes of a female protagonist who transforms?". She performed a mix of "lively" and "heartfelt" songs, including "Every End of the Day", "You & I", "The Red Shoes", "The Shower", "Knees", "Bad Day", "Obliviate", "Red Queen", "Everyone Has Secrets" and "See you on Friday". She also sang "My Old Story" and "Meaning of You" from her remake album A Flower Bookmark (2014), as well as a medley of the theme songs of Sailor Moon (1992–1997), Cardcaptor Sakura (1998–2000) and Yumeiro Patissiere (2009–2010). She ended the show with her hit song "Good Day". IU came back on stage for the encore and performed "Heart", "Glasses" and her unreleased song "Drama", which would later be featured on her 2021 EP Pieces.
Among sets, IU took the time to interact with the audience and share personal stories. During the first concert in Seoul, Dynamic Duo joined IU on the stage for "Leon" and performed their songs "Jam" and "Friday Night". Several celebrities made guest appearances during the two-day concert in Seoul, including IU's boyfriend at the time Chang Kiha, Kwon Jung-yeol of 10cm, Yoo In-na, Ji Hyun-woo, Han Seung-yeon, Goo Hara, Lim Seul-ong, Baek A-yeon, Hyukoh, Epik High and GFriend.
The tour attracted 15,000 spectators for the first five performances. IU's vocals and versatility were praised. Choi Hyun-jung of The Dong-a Ilbo said it was "a concert that combines story and song". The concert held on November 21 was IU's first public appearance following the scandal. After a discussion with her music director, she decided to include "Zezé" in the set list despite the controversy. Critics commended IU for her decision, which was perceived as a bold move from the singer that showed "the affection and sincerity she had for this song". Choi Hyun-jung wrote, "IU is a singer with a much stronger mentality than we thought, and at her concert that day, she overcame her burden with her sometimes strong and witty appearance".
This set list is representative of the show on December 4, 2016, in Seoul.
