You got forced married with a guy who was really cold and stern. Actually, his dad made you marry him because his dad paid your father with a lot of money. Mr jeon told your dad to make you marry him. The wedding simply happened with some marriage papers and nothing else. Right after getting married to Jungkook, you both had to go to south Korea as Jungkook had his business there. It was your first night with him and his family rituals were to do it at first night (forcefully)

Jungkook: let's just end this night Jungkook says rudely and takes his shirt off, staring at you Jungkook: don't waste the time, let's finish the rituals.
