What Should I Do If I Fall for My Best Friend's Twin Sister?

A sunny, simple-minded, gravity-powered male lead vs. a clever, flighty female lead

Before Xing Rongyu met Lin Huan, he was a fool who only knew about video games and basketball. After meeting her, he started getting sentimental too.

"Bro, don't worry. I'll take good care of her."

Her brother-in-law gave his friend, who'd been played into an idiot, a sympathetic look. He still couldn't put his mind at ease, so he warned his younger sister not to take things too far.

Lin Huan: "You know I've never had any toys since I was little."

She's grown up, sure, but what's wrong with letting her play a little?
