What is this story about?:

It's about a loving couple (Jikook) who have been dating since their debut. Up til now their relationship has grew more stronger. One day on November 2nd 2018 JK's dad recently got a brand new job in the USA & he wants to bring his son along with him meaning that JK has to give up his own career and live with his dad for a few days or even for weeks. They'll be continuing as 6 members and will now perform without him. This is definitely the most saddest moment for Bangtan. But...what happens when JK comes back a lot sooner than what everyone else thought? Will Jikook meet again or will they be separated for eternity? (Don't worry! There will be a very happy ending!)
