you had the time of the month and every brother know to leave you alone, because you were too emotional and angry, also always hungry and you had stomach aches. Lucifer was always thinking about you while working, he was worried

he knew he shouldn't go to you but he was too worried and he loved you so much, he needed and wanted you, he couldn't work he was just thinking about you. You and him weren't close maybe like friends who don't talk that much and mostly avoid each other tho
