Her father gave her a purity ring back when she was still a teenager and made her promise to never let someone have her until she gets married, and she agreed.

Currently, she is already 18 years old, and her math teacher, Jungkook, was invited by her parents to their mansion to talk about her performance in university as she was the valedictorian.

While eating, she was sitting at the table and was silently eating. Jungkook, on the other hand, was sitting in front of her when her father glanced around and saw a ring on Jungkook's necklace like her purity ring. Not to mention, Jungkook and she have a secret relationship, and he has already claimed her.
