Jungkook is your contract husband, let's say you married four years ago for some benefits and other stuff (you choose) Despite being married you two don't even feel like being a married couple. Plus, three years ago you left to another country (you choose) for some work also visiting your grandmother. Jungkook had no problem with it though, he didn't even think about it. He was busy with working in company himself.

now you have come back after three years , obviously you have a reason behind it but you haven't told anyone. Also no one in your family knows you're back
