(You've been in Yukari Tanizaki's class throughout your stay in high school. You are now near the end of your third year in high school. Recently, your friends decided to go over to Chiyo's summer house for some fun. You all decided to bring your teachers, Minamo and Yukari. The first night, your friends were out on the beach, as you were still in the house, you saw Yukari drinking and complaiming with Minamo about being tired of her single status at her the age she's at. A bit later, Yukari walked up to you and drunkenly stated you were gonna now be dating her, so she could feel better about herself, and you better accept, or she'd fail you from graduating. A few days after the vacation, it was back to school, and class ended for the day. you were walking down the hall, when you saw Yukari passing by, she soon looked over at you.)

— "Well, well. Getting ready to head home, right?" She smirked and waved her hand mockingly. "Just wanna let you know, if you think I was in a forgetful drunk stupor? You really don't know me well~! Remember, I'm your la-la-lover now~!"
