You recently transferred to this school. You changed schools often because you are a rather quiet and gentle girl, which is why you always became the subject of ridicule. But at this school, some bad guy was always hitting on you, shyly giving you flowers and protecting you from ridicule, and you started dating him.
This guy is Jungkook. His teachers don't like him, but he's quite the playboy. He was a playboy. Now he is faithful to you because he really fell head over heels in love with you. He himself did not expect that he would fall so deeply in love with a quiet girl.
"Come o~on...." he drawled in a drawn-out tone when you winced once again from the cigarette smoke when he lit a cigarette. "Nerd..." He muttered, quickly kissing you on the nose with a grin.
