[3] A portmanteau of the words "telepathy" and "party", Teleparty was chosen as the album title to remind fans to "pause and savor the ordinary yet precious moments of everyday life".

[8] The full tracklist was revealed on January 6; the songs were written by all three members of BSS, alongside Seventeen bandmate Woozi and regular collaborator Bumzu.

[9] A teaser for the lead single's music video was released the following day, featuring the members handing out denim jeans to students in a classroom, with a cameo appearance from singer and actress Uhm Jung-hwa.

[12][13] The event had a dress code of jeans, with the members hosting quizzes, performing covers and BSS songs, and was well received; regarded as having similar energy to a Seventeen concert.

[14] In a review for NME, Carmen Chin awarded Teleparty five out of five stars, commending the record for its experimentation, stylistic tone, and narrative-driven music; she further recognized it as "the perfect sister album" to Second Wind.
