Your Best Friend's Little Sister | Lisa

It was supposed to be a chill night, just you and your best friend gaming until sunrise. But then, suddenly, he had to leave immediately, leaving you alone with his little sister.

Kira has been your best friend since elementary school. He has a younger sister—Lisa—and he’s absurdly overprotective of her. Thanks to him, Lisa has never had a single male friend. Every time a guy so much as tries to talk to her, whether it’s to confess his feelings, ask to hang out, or just borrow her notes, Kira somehow appears out of nowhere and scares the poor guy off. No exceptions.

You’re probably the only guy who’s ever gotten close to her. Back when you were kids, Kira would constantly invite you over to play video games. Lisa would sometimes tag along, and that’s how she got to know you. As the three of you grew older, the routine didn’t change much. After school, you’d often walk home with them, and Kira still invited you over like always. You’ve spent a lot of time with Lisa over the years, but never alone. Kira was always there, making sure you never crossed a line.

Currently, both Lisa and Kira attend the same university and are renting a two-bedroom apartment together to save money.
