Lee Minhyuk (aged 20): Sometimes a jerk, sometimes adorable.

He looks too much like HIM - so much that even her heart becomes confused, and she finds herself blushing whenever he attempts to talk to her. She knows that both of them are players, and she know that both of them hate her guts, but she just can't stop herself...

Likes: flirting, taking selcas, sweet foods, exercising, BTOB members, and rapping.

Dislikes: quiet people, complicated situations, and clingy girlfriends.

He's handsome, playful and energetic - there is no deep and thoughtful side of him, but being around him definitely makes you happy!

Yook Sungjae (aged 19): Forever the cutest and youngest.

Always gets what he wants with his aegyo, and basically treats all of his hyungs as if they're his soft toys and teddybears: He's not afraid to kiss and hug ANYONE in order to achieve what he wants.

Likes: Cute things, toys, food, singing, rapping and snowboarding.

Dislikes: Girls (the loud ones), chocolate, pink and BTOB members (so he claims anyway).

Sungjae is cute, talented and considerate - but he has his masculine side despite the soft personality.   

Lim Hyunsik (aged 21): Think he looks like a flirting bad boy? WRONG! He's the sweetest gentleman on earth!

Opening doors, pulling out chairs, shielding others in times of possible danger; Hyunsik acts like he's a 30 year old married man, despite being only a year older than Minhyuk and Hei. He loves music to the point that he could sit at the piano for 8 hours a day, surviving only upon water and the sound of his voice intermingling with the notes.

Likes: Quiet and filial girls, singing, composing music and Yook Sungjae.

Dislikes: Being mistaken for a dodgy person because of his muscular build and small eyes.

Hyunsik is the ideal husband: intimidating to enemies, but sweet and responsible to his dearest people.

Hei (aged 20): Confident would be the last adjective used to describe Hei.

She is sweet, observant, responsible and has loving parents, but due to a certain incident back in her last year of high school, she is very careful in everything she does, easily scared, insecure and shy to extreme levels around men. With females she's best friend material: a reliable shoulder to cry on, a knowledgable head upon her shoulders and a beautiful yet make-up free face. 

Likes: Writing, singing, cooking and watching dramas.

Dislikes: Men.

A beautiful and kind girl who has many close girl friends, but no male friends - even shy around her own father and brother.

Lee Byunghun (aged 21): 

The cause of Hei's misery.

A complete player and knows no sympathy because his family is filthy rich and can buy him out of any type of trouble he finds himself stuck in.

Likes: hot girls, kissing and certain 'night activities'.

Dislikes: quiet and reserved girls, smart people, caring for others, and all BTOB members apart from Minhyuk.
