You (Kim Hana) are a second-year overseas transfer student at TS Arts College. Everyone around you sees you as one of those fake, tough girls who act innocent to fool the gullible and get out of the trouble you caused yourself. But what if you weren't acting? What if you actually had a… … split personality? Or something along the lines of two different people being trapped in one body?

Based loosely on the manga 'Othello'.

Kim Hana (You) (19):

Quite the average everyday 19-year-old Music major at college -- that is, minus the fact that you have a split personality. Your real personality is that of a kind-hearted, sweet, considerate young girl who is rather socially-awkward and loves music.  You are acutely aware of your disorder -- as you often wake up to ridiculous stories of what you have apparently done during the blank spots in your memory. You are a fast-94'er like Youngjae (in other words, you were born in the beginning of the year sometime so you started school early).

Bang Yongguk (23):

Your non-blood-related cousin who lives in Seoul, South Korea. His adoptive parents passed away a few years ago, leaving him their estate and inheritance -- to which he used wisely to open his own underground club featuring young people talented in music and entertainment of the sort. Knows of your 'condition' and really cares about you like an older brother.

Kim Himchan (23):

In his final years of his traditional music course at TS Arts College. Helps out at Yongguk's underground club and lives at Yongguk's place along with the other boys. His playful, 'don't-take-things-seriously' nature gets on Yongguk's nerves at times and has even been threatened to get kicked out of his house.

Jung Daehyun (20):

Also a second-year Music major at TS Arts College. He initially also mistakes you as one of those fake, tough girls who put up an innocent act, but eventually realises his mistake and finds interest in you. Met the others through Youngjae who's also in his college course. Lives with Yongguk and the others.

Yoo Youngjae (19):

A second-year Music major like you and Daehyun. His family owns the Yoo Electronics Corporation, which is an internationally successful Electronics company. Studying music as an interest since he wanted something to do before inheriting the company's business in the future. Supplies the tech for Yongguk's underground club. Lives with Yongguk and the others.

Moon Jongup (18):

A first-year Dance major at TS Arts College. A happy-go-lucky guy with an innocent smile who is the typical nice-guy next door. Knew Junhong in high-school and met Yongguk together with him at his underground club. Lives with Yongguk and the others.

Choi Junhong (Zelo) (17):

A second-year at TS Arts Highschool. Talented in rapping and dance. Has a slight mischievous-streak to him -- which influenced him to find a loophole into Yongguk's club while underage along with Jongup. Lives with Yongguk and the others.
