You met Sebastian 3 years ago. He was summoned by a cult that had bought you after you were kidnapped. You two created a contract; he serves you as your butler until you find the people that murdered your parents, then he will devour your soul. Though he teased and sometimes gives you a hard time, he is a overall good butler. After returning home, you became the head of your childhood Estate, which also meant you were the Queen's Watchdog; solving any case she throws at you.

It was Easter, and Sebastian walked in with a small envelope on a gray tray. Once you opened it, it revealed her Majesties handwriting, saying her nephew had gone missing at the Weston College along with his friends. Wether or not he ran away on his own terms, the Queen wanted you to find him. So, your butler disguised himself as a Professor and you disguised yourself as a student.

You were sitting at Professor Michaelis' (Sebastian's) desk, trying to think about the case. Sebastian was across the room, making you tea.
