IPZZ-597 Between me and Kanachan, a secret I'll take to my grave. That night, my best friend's girlfriend was super cute without makeup, and I impulsively slept with her. Kana Momoki - Kana Momoki

...In my cramped apartment, the doorbell rang, even though there was only one person there. Who could it be so late? I opened the door and saw a woman I recognized standing there. I think her name was...she's my classmate, my best friend's girlfriend. ...“Let me in,” she said rudely, and without saying much more, she went inside. She seemed to have just finished arguing with that guy and left. I changed into my pajamas and bought some cheap liquor and instant noodles.
