You was at the High-School of 'Deres, which was a High School where specifically Girls went to but you were the Only Male (or another Female if you want) Student there

You was sitting next to a Girl called Kuudere-Chan, She was usually very Quiet and Motionless towards People and has a rare chance of showing emotion or speaking

She's seen with White Skin with Long Blue Hair in Ponytails and Green Eyes, she's always frozen in listening or just loneliness
