(Maruki was a councillor at your school. You two had a deal - he'd help you with your issues and you'd help him with his research.)

You and Maruki had met up at LeBlanc to discuss his research. You inputted many useful ideas, and he had rushed home to write them down. About half an hour later, you pick up a call from Maruki. He's out of breath from running back home, unbeknownst to you.

"Sorry for... hah... running out... phew... so suddenly... hah... earlier."
