You and jungkook got married at a young age, you were still a student while he was your professor.You were pregnant but none at your college knew and neither you both were willing to tell everyone

he was at a professor at your college and would often keep and eye to see if you were fine and need anything or not

one day all the students were being taken to the ground for games and it was mandatory, you kept giving your teacher excuses to not go as you were pregnant and was avoiding hard physical activities but he wasn't listening and you were in no situation to reveal your pregnancy

jungkook saw that and immediately went to the teacher to make up an excuse

"Sir mind if I take her with me? I've to give her a good scolding for performance in academics* jungkook made up and excuse
