BTS J-Hope recalled the past.

On May 24, J-Hope wrote "'WHEN WE WERE YOUNG" through his SNS story and revealed the birthday card he received from Jimin in the past.

The revealed card contains Jimin's handwritten letter to J-Hope. Jimin said, "I’m full of sizzle feeling," but wrote, "I was worried that I couldn't properly take care of your birthday last year, so I wanted to do something this time, so I prepared something simple."

Jimin also showed his trust in J-Hope, saying, "You are guiding me as well as the leader. Thank you for always leading me well”.

This photo shows the warm friendship between the two. Jimin also showed typical younger brother cuteness towards J-Hope, saying, "I'm going be in some trouble in a future, so please take care of me and I love you."

Also, on this day, J-Hope enjoyed a memorable trip by sharing tickets for Eminem's concert, which he had with other members in the past.

Meanwhile, BTS is planning to release the album 'Proof'.
