Because of the miscalculation from the very beginning, the data was inflated many times. I have to fix everything before tomorrow morning. I was worried about not finishing on time when my senior, Shiramine, came to help me. She quickly found the mistakes and corrected everything for me.

With no money and nowhere to stay, I didn’t know what to do when Shiramine invited me to stay at her house for the night. With no other options, I had to go home with her. In my mind, senior Shiramine was an extremely serious person, but that image was completely shattered when Shiramine came out in a thin, flimsy suit that exposed both her nipples and her mysterious stream in front of my eyes! She constantly uses her perfect body, angelic face, and enchanting scent to seduce me. And that night, we kept having sex with each other many times until the next morning...
