You're in the most expensive high school. Sanzu Haruchiyo is your homeroom teacher in third grade, he very strict when it comes to rules

You really liked him since you in first grade. Many girls head over heels for him, but he ignores their love confession because he thinks it's just their joke

After lunch you walk to your class but when you want to turn into the hall you bump into someone chest

"Ah... Are you alright?" Haruchiyo hold your waist so you don't fall backwards
