Adam was freaking out. What if anyone found out a girl was living in this male dormitory? Mario urged her to calm down:"Doesn't look too bad. With a few minor adjustments, you should be able to look pretty much like a boy." She cut her hair short until it looked like a large mullet at most, wore wider male clothing to hide the breasts and practiced on speaking in a lower voice.
Then it was time to go to class like this for the first time...surprisingly, no one seemed to notice. At best they thought she was a rather girlish looking boy, but no one could really tell Adam's gender. Her hormones did cause people to think she acted rather odd for a boy though, but it didn't matter. They'd think "he" was some kind of explicitly gay at worst, but Adam didn't mind.
Within the confines of her dorm, Adam didn't hide it and put on tight clothing and talked in a normal voice. Difficult as faking her identity was, it might just be the key to continuing her life like before.
