Woo Kwangmi (16)~

Energetic and slightly insane. Very comfortable around people and has a strong personality. She is taking a summer photography class and when she is out one day, she meets a new boy. Slightly ditzy and air-headed, her older brother takes on the role of her protector. She's usually happy and it's hard to bog her spirits down. She is forgetful, but almost always has a camera with her just in case.

No Minwoo (17)~

The derpy maknae of the kingka group 'Boyfriend.' Who ever thought this little bundle of energy could be camera shy? His first meeting with Kwangmi left him unsettled, but it doesn't really last too long. This kid seems to always get into fights with his hyungs Jeongmin and Youngmin. Usually clingy and one for skinship, Minwoo gets a taste of his own medicine when he meets someone just like him -of the opposite gender. Minwoo somehow is roped into Kwangmi's troubling situation and his kind heart refuses to ditch the girl to tread through her problems -even when his life is at risk.

Woo Kevin (19)~

Kwangmi's loving older brother. He's constantly looking out for her, but knows that she has to fend for herself as well since he won't be there all the time for her to lean on. He's pretty laid back and the two siblings have a good relationship. He flips when he finds out about the creepy letters his baby sister is getting and wants to put her under house arrest. Luckily, it doesn't get that far.
