The first leg began on 29 May 2024 in Lisbon, Portugal, and concluded on 28 June in Birmingham, England.

For opening night, Kevin LeBlanc of Nylon praised Sivan's "homoerotic fashion choices" as "tasteful" and "simple yet affective" and wrote that Sivan delivered on "the queer Bushwick-meets-runway fashion" of the album cycle and the "gay pop star fantasy with a now-signature recipe: a dash of George Michael, a hint of ‘90s runway fashion, and a sprinkle of Berlin club attire".

[3] For Attitude, Alastair James favourably compared Sivan's show to Dua Lipa's Future Nostalgia Tour, stating that Sivan showcased the same "bonafide star quality" Lipa did at the AO Arena two years prior and that Sivan could "do it all – the party, the love, and the heartbreak", though noted that the show felt a bit reserved due to the lack of a bigger stage and that it could have gone longer than the compact setlist allowed it to but nonetheless praised the show as a "spectacle" and a "sweaty and euphoric party".

[4] Flo Laurent of Hot Press described watching Sivan be "unapologetically queer" as "deeply heart-warming", especially a few days before Dublin Pride, and praised his range as a performer and his ability to let his dancers shine.

[5] Charlie Duncan of PinkNews described the show and Sivan as both "hot and gay", the choreography as "crisp" and "so intense it looks like you’re watching a real life music video", the different outfits as matching Sivan’s "effortlessly cool and gay" aesthetic, and praised Sivan's ability to "marry vulnerability and vocals with sex and stardom", noting the more intimate tracks being preceded by private-life insights from Sivan himself to draw the audience in, though criticized the Ariana Grande section as "flat" due to the lack of Grande's presence but noted it as only a "minor misstep" quickly forgotten by the changing sets, the "horny dance moves" with Sivan grinding on or snogging dancers as almost "too scandalous to watch", and the guest appearances from Ross Lynch and Charli XCX at the OVO Arena Wembley show.
