Jang Yoonji is the step-sister of Infinite's Dongwoo. She has been invited by Dongwoo to live with him and the other members of Infinite. All of the members capture Yoonji's attention in different ways. Sungjong is cute, Sunggyu is attentive, Hoya is laid-back, Sungyeol is childish and Myungsoo is friendly (and handsome). But the member who (annoyingly) stands out is Woohyun. He's flirty, y, greasy and a big tease.

To Woohyun, the fact that L stands in his way in getting Yoonji to fall for him is frustrating. Sunggyu, Woohyun's closest friend in the group knows all of his darkest secrets. What is his biggest secret? Why doesn't he tell anyone? Will Yoonji hate him or love him?

"Woohyun, you're in love. Just give up your heart." - Sungjong

"You're not allowed to flirt with her, kiss her, , or touch her any more than you have to." - Dongwoo

"What the hell?! Did you think she'd be okay with this? Did you ever even think of how she might feel?" - L

"Even though you like L, I will make you fall for me," - Woohyun

"I bet you say that to all the fangirls." - Yoonji

"Honestly, I would go through anything just to change your mind." - Woohyun
