Seokjin unintentionally helping them to overcome their disorder or just even helping them to not lose their appetite :( #EatJin5thAnniversary #5YearsWithEatJin pic.twitter.com/bEbHQ3L6nB— ً (@jinakgay) May 20, 2020The army, however, is extremely smart and eagle-eyed as they adeptly deduced the elusive collaborator's identity. The head of this person in the picture, which is as far as the fans can see, resembles an artist whom everyone including BTS idol Jin is a fan of.This led fans to believe that BTS will collaborate with Coldplay star Chris Martin. The rest of the snapshot, however, was hidden by an animation on the clear case of BTS's new single "Butter."Fans of Coldplay and BTS also realized that the former's upcoming album is set to be released on October 15, and the title is "Music of the Sphere."During the concert, Jin also brought back his famous mukbang Eat Jin, and ate egg tarts. Fans had previously shared that Eat Jin helped them overcome their eating disorders. Watching the star eat during his Mukbang Vlogs helped many overcome their apprehensions surrounding food. The BTS star also made a call to Bang Si-hyuk, aka Bang PD, and wished him a happy birthday.
