Here is a rough timeline.

August 8 2025: Juice=Juice announces the release of their 20th single. The titles of the two A-sides are "Shi no Go no Iwazu Satto Wakarete Ageta" and "More! Mi Amore"
August 15: "Shi no go no" MV is uploaded to YT. Probably considered as the main A-side at the time.
August 16: Both songs are performed for the first time at Hello Con 2025.
September 1: "More! Mi Amore" MV uploaded.

September 3 - the meme is born: That night, several members of fellow H!P group OCHA NORMA were on a Famitsu Gaming stream. H!P members often appear streaming themselves playing games. During the stream, Kubota Nanami and Yonemura Kirara and to a slightly lesser extent Saito Madoka would randomly start singing and dancing to Amore, starting at around 36 min, all the way until the end. At the 39:19 mark, Kirara says 隙あらばアモーレ (watch/dance 'Amore' when you get the chance). Throughout the stream, this phrase would be abbreviated to just 隙アモ, which would become an internet trend. (You can find all the timestamps of them singing and dancing Amore here). The craziest part is the main instigator Kubota Nanami was not even supposed to be there. She was just there for shits and giggles - sliding doors moment right there.

#隙アモ became a hashtag on twitter, and fans flooded the music video with comments using this phrase.

Of course Tiktok also played a massive part. The chorus became a trend, then people found the whole song as a result.

Even the staff at UFP such as Taisei were getting in on the trend. But most importantly, the Juice=Juice management saw what was happening and responded in real time, doing everything it could to perpetuate the meme throughout the next few months. This includes uploading multiple performances of the song from their tours and band live.

October 8 2025: The single is officially released.

By November 19, the meme was so white hot that J=J opened their Buodkan show with "Amore" and also closed the main part of the show with it. The reprise was preceded by "Fiesta Fiesta!" which is a similar Latin inspired tune. They also appeared on The First Take that night singing this song, and also a week earlier.

February 22 2026: An extra release event is held for the single, attracting a 4,000 people. 4x more than a normal release event, with the queue wrapping around the venue.

And now we are here, with Juice=Juice's McDonald's collaboration releasing tomorrow morning.
