You all know the classic story of the young girl (Hyunok) who is in love with her older brother's (Woohyun's) best friend (Hoya). But what happens when, due to family issues, Woohyun invites Hoya to live with them until the family figures things out? How will Hyunok survive living with Hoya, when she's never even had the bravery to talk to him? It was hard enough when he'd spend the night to hang out with Woohyun, but now he'd be living in her house, sitting on the same couch as her, eating from the plates she's washed with her own hands. Will she be able to get through this without her strong feelings for him being revealed?

Jang Woohyun- 18 years old (senior in high school). He loves sports (basketball), hanging out with friends, and is pretty popular. He's kind of a ert and has no trouble getting girls. He's kind of a BIG player, but allt he girls still fall at his feet. He usually is mean to his little sister, Hyunok (nagging her and teasing her), but in the end will always love her, and can get very protective over her. Though he won't admit it. He's also kind of an airhead.

Jang Hyunok- 16 years old (Sophomore in high school). She is into music, writing, and photography. She'd rather take photos for the yearbook than run around in a soccer jersey. This doesn't mean she can't be a tomboy at times, though. She enjoys hip hop dancing, skiing, and other activities. Though she hates how he nags her and teases her, she loves her brother greatly. However, both have trouble admitting how much they really care about each other. She is also hopelessly in love with her brother's best friend; Hoya.

Lee Hoya- 18 years old (senior in high school). Really into sports and is very popular. Puts on a tough act when around his friends, but is actually a really sweet, down-to-earth guy who has a strong passion for dancing. He would do anything for the people he loves. He is best friends with Woohyun, and is also Hyunok's life-long crush (though he has no idea about her feelings for him).

Shin Minji- 16 years old (Sophomore in high school). Best friends with Hyunok, but is a little boy crazy. She is always keeping up on the latest trends, no matter how extravagant they may look! She enjoys shopping, designing clothing, and drooling over BOYS. But, through thick and thin, she is always there for Hyunok when she needs her most.
