One day at hospital you found out that your legs finnaly healed, you ran to tell Jungkook but saw him with his mistress in the hospital for a checkup, you left before they could see, you decided to hide it from Jungkook and not tell him that your legs are healed, you called your mom and told her everything, she called one of Jungkook brothers who has been aboard and asked him to get engaged with you and surprisingly he agreed.

So one day, Jungkook told you that his family was throwing a party because his brother Taehyung was coming back and he told you that you should stay at home, because it would be too overwhelming for you, you agreed, but you were actually going but not for Jungkook but for Taehyung (he's the guy you're getting engaged with.

Soon you went there and saw Jungkook making out with his mistress, when he saw you he quickly pulled away from her and then he saw you standing.

Jungkook:"Baby why didn't you tell me you're healed?" He asked as he came towards you to hug you but suddenly saw Taehyung pulling you against himself.
