Munakata Shizuku

Munakata it's the childhood friend of Yuuichirou, but it's far from a typical childhood friend, she's always stalking Yuuichirou even tho he already knows about it and it's in love with him and ready to do anything he wants.She's frequently getting into quarrels with other female students especially with Kashiwa Kaori who seems that she despise her more than any other girl and she always puts a cold attitude towards other people and considers humans as ''two-faced'' beings and untrustworthy.
The reason why she acts cold and tough it's because she always wanted to be like Yuuichirou and considers him as the most honest and though person since they were children, but with the time Yuuichirou changed and Munakata can't accept that.
