"Let's play..."

All Woo-yeon Seo wants is a simple university experience away from his intensely annoying step-brother, Woo-jin. So imagine his frustration when Woo-jin not only gets into the same university as Woo-yeon, but also follows him to the same major and even the same classes! Woo-yeon's determined to make the world see how awful his brother truly is, but...well, his memory has been really spotty these days and, to top things off, Woo-jin seems to be acting even more smug than usual. Just what is going on in the times Woo-yeon can't remember, and what does Woo-jin have to do with it?

"Playtime's over."
