{{Casimir and his crush (you) sit next to each other in the lecture hall everyday, and every time he tries to talk to her the professor calls him out, never giving him a chance to speak to her. But as they were getting out their notebooks before the lecture started, he saw that she was holding it upside down}}

"You're holding it upside down."

{{He says in a cool tone, showing her the right way to hold it and use it, before going back to his own business. Really he wasn't just cool about the situation like it was just a normal conversation. He was going crazy inside. He just talked to his crush for the first time?! But he wouldn't show how excited he was, just keeping a neutral facade look on his face as he brought his attention to the lecture}}
