An editor of Antena 1 called the track a "phenomeon", while an editor of Libertatea wrote that "Tornerò" remains "the best-known song by a Romanian artist at Eurovision". An author of Tribune Business News considered it "probably has one of the most haunting refrains among all the Romanian [Eurovision entries]". Including the single at number four in their list of "Eurovision [2006]: Top 10 Tips", BBC praised Trăistariu's vocals as "soaring", as well as the song as "the most contemporary offering [in the contest]". The website further wrote: "Something about this makes it hard to forget – a very high scorer." Ioana Matfeev of Top Românesc slightly criticised Trăistariu's diction in the song. In a 2016 poll on Wiwibloggs called "What is your favourite Eurovision song from Romania?", it finished in fourth place with over 500 votes. According to Giannis Argyriou of EuroVisionary, "Tornerò" remained popular among Eurovision viewers, while fans of the song include Romanian singer Alexa and Romanian music critic Liviu Zamora; the latter praised Trăistariu's emotional delivery.

Trăistariu made appearances to perform "Tornerò" on multiple occasions throughout the years, along with other endeavours. An accompanying music video for the song was also filmed sometime in 2006, with it being included on a CD release of the track in the same year. The visual portrays the singer lip synching to "Tornerò" while walking in a hallway with dancers and other people, occasionally interacting with them and joining their activities. Trăistariu recorded a duet version of the song with Greek singer Tamta titled "Tornerò, Tromero", while covers were done by artists including Greek recording artist Anna Vissi, and Romanian singer Lora during Romanian television show Te cunosc de undeva!.

On 26 February, the Selecția Națională was organised by Romanian Television (TVR) to select its song and performer for the for the 51st edition of the Eurovision Song Contest. "Tornerò" was chosen after the votes of a professional jury panel (12) and public televoting (10) were combined, resulting in 22 points. Prior to being selected to represent his country at Eurovision, Trăistariu had participated in the Romanian national selection multiple times. Romanian-American singing-songwriting duo Indiggo, who placed seventh with their song "Be My Boyfriend", sparked controversy after demanding €100,000 from TVR for allegedly not being votable by fans due to continuously busy lines. Their allegation was turned down by TVR.

The Eurovision Song Contest 2006 took place at the O.A.C.A. Olympic Indoor Hall in Athens, Greece and consisted of one semi-final on 18 May, and the final on 20 May 2006. According to the then-Eurovision rules, selected countries, except the host country and the "Big Four" (France, Germany, Spain and the United Kingdom), were required to qualify from the semi-final to compete for the final; the top ten countries from the semi-final progressed to the final. In 2006, Romania automatically qualified to the final due to the top 11 result last year, where Trăistariu performed in 12th place, preceded by Macedonia and followed by Bosnia and Herzegovina. At the close of the voting, it had received 172 points, finishing in fourth position and thus qualifying the country for the final in the next contest. "Tornerò" received points from 35 countries with Moldova and Spain awarding the maximum 12 points to the entry.

Onstage, Trăistariu was accompanied by three male and two female dancers from Romanian dance group Big Bounce, who performed choreography done by Romanian singer and choreographer CRBL [ro]. It contained elements from both ballet and contemporary dance, and was meant to "highlight [...] Trăistariu's song and voice." Over the course of the preparations, dancers were partially replaced. Romania's first rehearsal took place on 15 May 2006 to positive reactions from the audience. Various changes concerning the staging were also made on the same occasion. In a review of Trăistariu's show, Caroline Briggs of BBC compared his look to a "ginger" Justin Timberlake.
