Sleuthing ARMYs used all of their detective skills to find out who BTS V's secret muse was. They succeeded.

According to a report by Koreaboo, fans have been curious to know whom BTS V or Kim Taehyung was addressing during an impressive performance of two popular opera songs.

After his performance of "This is the Moment" from Jekyll & Hyde and "Nessun Dorma" from Turandot, he addressed a woman named Elizabeth. To the woman, he solemnly promised that they will meet again.

At first, fans thought that Elizabeth was from the plays but it turned out that both stageplays never had characters named Elizabeth. Even Jimin was puzzled when he mentioned the name.

Thinking that V may have been referring to a mysterious muse, fans tried to find out who the woman was. After diligently researching all possibilities, ARMYs may have found the answer.

V could have been referring to Elisabeth, the titular character from a German musical about the death of the Empress of Austria. Elisabeth was married to Emperor Franz Joseph I.

V may have become familiar with the character while supporting his good friend Park Hyung Sik. Hyung Sik appeared in the South Korean production of the stage play in 2018 and took on the role of The Death.

It is well known around the entertainment circles that V is the youngest member of the Wooga Squad, a group of friends composed of actors Park Seo Joon, Choi Woo Shik, Park Hyung Sik, and rapper Peakboy. The squad members constantly support each others' projects and attend everything from BTS concerts, stage plays, and radio shows.

Early this year, V wrote and recorded the song "Sweet Night" for the OST of Park Seo Joon's Itaewon Class. The song earned Kim Taehyung the honor as the first male soloist to top the iTunes chart in 105 countries, All Kpop reported.

V is currently preparing for BTS' November comeback with the album BE, which will showcase music written and produced by BTS members during the height of the COVID-19 pandemic. Big Hit announced that the album will feature the most BTS-esque music ever which seeks to inspire the fans during a time of great crisis.

V is also busy working on his first solo mixtape which he wants to release before the end of the year. V said he already wrote eight songs for the album and teased snippets of the tracks in BTS' online videos, Elite Daily reported.
