Amber is desperate to make money for her sick grandfather who is in a coma. She came across a sign that says 'Help Wanted! We need boy workers!' that was infront of a cafe named Lucky Love. She thought she must have gone crazy when she applied for the job and potray as a guy. Until, Taemin and Kris came to the cafe. 

Taemin and Kris are half brothers and they started working at the cafe where Amber works. Their grandmother made them applied for the job, so they know how it feels to work. 

Taemin and Kris are totally opposite: Taemin is jerk while Kris is nice; Taemin is Korean while Kris is Chinese. 

Kris and Amber got along well together because they can speak in Chinese and no one will know what they are saying. Same thing with Taemin, they speak Korean to each other, but it's hard for them to hold a conversation togehter because they'll end up arguing. 

Amber has fallen for Kris, but at the same time, she started have feelings for Taemin. 

One day, Amber went to the locker room to change, making sure no one is around and closed the door behind her. She didn't notice the door didn't closed all the way when Kris accidently saw Amber changing and he realized she is a girl. He kept it a secret from everybody, even Amber. 

Kris has fallen for her once he found out. Taemin was falling for Amber, too, she has those charms that Taemin looks for in a girl, but there is one problem: they're both guys. 

Will Taemin finally realize he's not gay? 

Will Kris confess his love to Amber? 

Which guy will get Amber's heart?
