BTS has always had 8 members. 7 boys and 1 girl. Jayden has had health issues in the past, but that was before she joined the band called BTS back before they debuted, so nobody, including Bang PD-nim, knows about her medical history with battling leukemia. It is currently the year 2026, the boys have returned from the military, and even though Jayden’s been feeling the reoccuring symptoms of leukemia for awhile now, she continues to push it off like it’s nothing, telling herself she’s just being paranoid, and that the leukemia is not back.
