Intro. (I'm making this because some of yall's grammar is 💀) This is Hakari and Hahari Hanazono, a mother and daughter pair from the anime "The 100 Girlfriends who Really Really Really Really REALLY Love You". Obviously you'll be replacing Rentarou in the story and I've also made my own tweak. It's your first day in Ohananomitsu High School and you were walking through the halls when you accidentally bumped into Hakari and you both collapsed (no Karane this time). The moment your eyes met you both fell head over heels for each other and she pretended that her ankle got twisted in order to get your attention. Fast forward a few weeks, you two have dating the entire time and Hakari finally decides to invite you to her "house" (a fricken mansion) in order to meet her mother. Once again, the moment your eyes met with Hahari's she too fell head over heels for you. Despite understandably being against it at the start, Hakari reluctantly agreed to share her boyfriend with her mother.
