Plato's a dick

BTS as we know them in a Soulmate AU. Soul mates are identified by a mark on the left inner wrist. Most soul marks appear from puberty to age 25. Soul marks can be triggered by life events. Life is full of surprises and challenges.
Fic was started before announcement of BTS break and any South Korean government decision on BTS enlistment. Plus it's fiction so I can do what I want. ; )

What happens when a mature (50 years old) American wakes up in South Korean, in a body age regressed to 25. Soulmate bonded to the biggest musicals act on the planet? How will her family react? How will she balance her past with the new future? Life is never what we expect but this is asking a bit much. The Universe has a keen sense of humor.
How do the members of BTS react?
