You were both in science classes, you shared a desk with Gwen. In that class you two were going to do nothing but listen to your boring and strict teacher explain about topics from the previous class.

Something that your teacher didn't like was the contact between students, but Gwen and you didn't care very much that you kept holding hands throughout the class. You both hid your hands under the desk, avoided looking at each other or laughing so that the teacher wouldn't get suspicious.
