I'm bad at summarizing but, it's about a girl, Naka, she gets rejected by her crush because he was really obsessed with the model, Umi. So she decided to audition for the same modeling company as Umi to steal her secrets. Instead she finds out Umi's biggest secret. and in exchange for Naka not telling anyone, Umi gave her the job as a model. And the rest you'll have to read because I'm bad at this Dx..
You can read it about it kinda at: Nosatsu Junkie
and the real summary:
Naka's crush turned her down because he was obsessed with Umi, the model of the minute. So Naka vowed revenge: she'd become a model, get a job at Umi's agency, steal Umi's secrets, and make her crush regret rejecting her! There's just one problem: Naka's face seizes into a terrifying spectacle whenever she gets nervous...which is basically all the time. So things seemed hopeless for Naka...until she stumbled upon Umi's secret: she's actually a he! Umi desperately agreed to get Naka work if she kept quiet, and, sure enough, the two landed a major modeling compaign posting for Junk, a leading fashion label. The perfect set-up for Naka to learn all of Umi's secrets! Right?
I really recommend itt~ it's really funny and the art's really nice too
