68 parts Complete MatureTaehyung and Jungkook end up with the same soulmate.
When you turn 21, the name of your soulmate appears on your body. Usually, you only get one soulmate but that's not the case with Emma. She ends up with not one but two members of BTS. She doesn't know the group, she just knows that two of her regular customers at the cafe, often stare at her and on the day she turns 21, two names appear in more than one place on her body. The noticeable ones are one on each wrist.
Taehyung and Jungkook have known for a while that the waitress at their favorite cafe is their soulmate. Her name appeared first on Taehyung since he is older and when Jungkook turned 21, he noticed the same name. They figured it was different people but with the same name. Their first time going to the cafe was shortly before Jungkook's appeared. When Emma came to take their order, each boy had the same reaction and had to restrain themselves. It was obvious that she wasn't aware that they were her soulmates. They discreetly asked one of her coworkers how old she was and they found out she is only 20. They continued coming in to see her multiple times a week while they were in town. She may not know but they wanted to be near her.
When they come in one day and see their names on her wrist, everything changes.
