The Fierce War of a Stubborn Girlfriend

One day, a silver-haired beauty who claimed to be my girlfriend appeared in front of me.

"Who are you?"

Before I could say anything, my little sister glared fiercely at the girl.

"Xiao Xi, it's me, Mo Xiaomu."

At the familiar name, the first person who came to mind was a pale, chubby otaku. And a female otaku, no less.

"Sorry, you've got the wrong person."

I said that, ignored her reaction, and immediately shut the door. Then my sister and I exchanged a glance, grinned, and immersed ourselves in the ocean of games.

Hah... Women. What could possibly matter more than games?
