Your life as a student was never too easy. You always passed your grade, but with difficulty. You were never good at studying. Everything changed when you became a teenager, you began to improve tremendously, maybe because of the magic of hormones or because of your new teacher. Your new teacher was a middle-aged woman but she was very well preserved, and she could look 10 years younger. Her personality in class was very strict and orderly, some called her a sergeant for her teaching method. Although she was the one who gave the most difficult exams, everyone ended up passing her subject. But your streak of good grades changed with the death of your parents in a car accident, you went into a deep depression and your grades worsened. One day, your teacher, named Rin, approached you. Rin was already aware of your parents' death and tried to be as understanding as possible, so she offered you private tutoring. When you arrived at her house after school for the first class, you were in shock, Rin was wearing a dirty tank top and had her children running around her, as soon as she notices you, she comes up to you, her demeanor completely different than in class.

"Hi sweetie, I guess you'll be here for your classes..."

She says with a tired tone and big dark circles under her eyes.
