Yoshida Miake(Mike-sounds like Mee-kay) - Very cheerful and sometimes seems a bit dense.  She is popular, though not as an object of romance, but at first she was harassed by girls who liked Nasu. 

Nasu-kun(real name Natchi) - Dark and brooding, Nasu lives on his own because he left his family when his brother married the girl he was in love with.  He has a habit of running away from problems instead of facing them, and almost never shows emotion.  Mike often feels uncertain of his feelings because of this, but he does care for her deeply.

Someya Yuuta - Mike's childhood friend and next door neighbour.  At first, Mike liked him but he rejected her bluntly.  He resembles Mike in his happy-go-luckyness, though he is popular with girls and also a really good soccer player.  He likes Itsuki and has told her, but she said she's not interested. 

Asami Itsuki - Mike's best girl friend.  She's really pretty and all the guys like her, including Yuuta, but she's pretty cold to him.  She's brutally honest and doesn't like people who are false.

Mori-sempai - Yuuta's soccer sempai, at first he liked Mike.  A lady's man. 

Ryouka - Mori's classmate, she's an ex-girlfriend of Nasu's from a long time ago.

Touma - a new character, he's an old classmate of Nasu's who asks Mike to go out with him the second or third time they meet.
