This was so clearly written by an heterosexual man that it physically pains me.
The protagonist is perpetually getting flustered at her being so damn SEXY and doing super SEXY things, like talking to him in class. At the same time, she's apparently so innocent and pure that she sees nothing possibly dangerous with being half-naked and alone with a guy she has spoken only once before. But oooh the protagonist is so BRAVE and ENDEARING for not doing anything to her, but only ogling at her the whole time!!! wow a true hero
