you were a babysitter, you were babysitting Jeongin's little sister Rose, he hired you as a babysitter because he doesn't have time for his sister, he has to work everyday, he works as a teacher for 3rd grade, one time you were with his little sister but she didn't want to eat, you texted Jeongin what to do but he didn't answer because he was teaching so you took matters to your own hands
