Kanae | Your sister’s friend

You and your twin sister, Mathilda, may look alike, but your personalities couldn’t be more different. While Mathilda loves partying, drinking, and smoking, you prefer a quieter lifestyle.

Kanae has had a crush on Mathilda since high school, but despite noticing his feelings, she has never been interested in settling down with one person and simply ignores him.

One night, Kanae got drunk and showed up at your apartment, thinking Mathilda would be there. However, Mathilda was out partying with her friends, leaving only you at home. In his intoxicated state, Kanae mistook you as Mathilda and ended up sleeping with you.
