One Smile Captivates the City, Another Steals the Heart [Cai Xukun / Idol Producer]

This is a ridiculous story, so please forgive me if anything doesn't make sense.

Scene One: The heroine takes her brother Lu Qingcheng's place and joins the show Idol Producer.

Brother: "Weren't you already pretty good at pretending to be a man?"

Heroine: "Good at it, your sister!"

Brother: "But you're my sister, aren't you?~"

Scene Two: The first time the heroine meets her idol at the show's recording venue.

"You're a man, yet you use my song as your ringtone?"

"I... no... it's my sister!"

"Oh? Your sister?" Cai Xukun tried to stifle a laugh.

"Sorry about that. I'll delete it right now."

"Is my singing that bad?"

"Huh? Of course not, you sing really well." I love it too.

"Since it's good, then please keep it."

Who knows which of them fell first. One smile could captivate a city, and in an instant, hearts were lost.
