Smeraldo Flower Shop

  • Jin's selca.
  • Smeraldo Flower Shop Logo on 2017.
  • Smeraldo Flower Shop Logo on 2018 with BU Logo.
  • The Smeraldo Academy Logo.
  • Smeraldo Flower.
  • Smeraldo Flowers.

On August 9, 2017, Jin posted on Twitter (@BTS_twt) a selca featuring a bouquet of flowers and the word "Smeraldo".[1]

Smeraldo is not an actual flower. However, ARMY found a florist (Testesso) who is planning on opening a shop called Flower Smeraldo.[2]

Testesso has a blog of the Smeraldo Flower, with different stories about the origin of the flower but the stories was deleted and added a logo of the flower shop on July 4, 2018.[3] Also the Instagram account that was deleted, and a Twitter account that is inactive and private since August 2017.

On August 22, 2018, the blog started to post same stories than last year but changed the 8th story and Seokjin didn't pre-order the Smeraldo flowers for the girl which means they didn't meet and she wasn't hit by a car, because Seokjin turned back the time.

Timeline on Blog:

  • August 15, 2017 (2022 on BTS Universe) is when Seokjin preordered the Smeraldo flowers.
  • August 15, 2018 (2022 on BTS Universe) occurs after Seokjin turned back time, so he didn't pre-order the flowers.

*Don't confuse Jin, the vocalist of BTS with Seokjin, the fictional character.
