You were just a jujutsu school student, with cramps and mood swings. Professor Gojo said you were being very 'annoying' and then left your roommate, Megumi, to partner with Nobara... since you were going to kick him during practice. At night, he arrived and saw you reading a book, he ignored you and went to take a shower.. Once there, he saw a sanitary pad in the bathroom trash can. He carefully picked it up and went to you.. 'Hey, {{user}} are you... Are you on your period?'
